Mizuno Wave Universe Review Update @MizunoRunning

Seven weeks since I wrote the last review on my Mizuno Wave Universe (WU) last. Now over 210 miles on WU4 and 190 miles on WU3, they are still going strong! Since many people are looking for a shoe review on WU and they seem to be concerned about its durability, I thought of writing a quick update. I mostly run on pavement (concrete or asphalt), so below should be representative of its durability as many people wear racing flat on pavement (right?), rather than strictly on track or soft trail. I’ve been running in WU4 on dry days and in WU3 in rainy days.

Wave Universe 4 midsole tearAt 210 miles, my WU4s are showing some tear and wear at the outside of the mid-foot: The black rubber-ish material you see in the picture on the left. I don’t know how many more miles are left in the material until mid-sole starts showing. The same deterioration is found on my other shoe; however, the same material on the front and inside still looks as good as new – almost.

Mizuno Wave Universe 4 soleThe outsole is still securely and tightly glued to the upper, and shows no sign of coming apart. This is the case all around the shoe. The same goes for WU3 I put through some wet weather, as well as washing machine and manual washing. One thing I noticed was I got a wet foot when I accidentally step on a mushy grass. As a result, I got a big blister exactly where the outsole is wearing out. I don’t know if the water came through the thinning outsole or the opening in the middle of outsole (I don’t know what it is called).

Mizuno Wave Universe 4 heelThe orange thermal plastic that runs from heel to midfoot shows a little bit of damage as well, but nowhere near as bad as the outside of the midfoot. I guess I am not a serious heel-striker. This thermal plastic material is pretty springy, so it is supposed to help when I am pushing off and moving forward.

Wave Universe 4 upperOverall, the shoes are still in a great shape. Except for picking up dirt stain, there is no functional damages in the upper. My feet are pretty wide, but they adjusted to the width of my feet and hug my feet every time I lace up. I am not showing WU3 but their upper does not have any damages, except it shows the dirt and stains much more due to its color.

I will write another update in additional 100 miles or so.

Mizuno Wave Universe 4 Review

Mizuno Wave Universe 4I bought a pair of Mizuno Wave Universe 4 in December last year since I loved its predecessor so much. Wave Universe 3 is great shoes. They are amazingly light and provides just enough support for me to run fast and not get injured at the same time. I knew about the upgrade earlier last year, but knowing WU4s are basically the same shoes with no significant upgrade, I decided to wait a little, especially MSRP was $120 then. However, as soon as I saw a price reduction ($89.97 on Amazon.com), I placed an order. Now, you can find them less expensive at Amazon, Running Warehouse, or other online retailers.

As I mentioned earlier, there are not many differences between WU3 and WU4. Technical spec on the manufacturer’s web site shows few differences. Their appearances are identical except for the color scheme and design/pattern. WU4 might be a bit heavier (3.9oz for WU4 vs. 3.8oz for WU3 in size 9). Heel to toe differential is the same at 5mm. They are both width size D, which is perfect for my feet. The toe pocket provides perfect room for my toes to fit comfortably in both shoes. I hear insole is different, but this is a moot point for me since I wear socks with these shoes.

Mizuno Wave Universe 4So far, I’ve run over 80 miles on WU4 and 130 miles on WU3. Despite the light weight, sole and cushioning materials seem to have weathered the pounding very well from running mostly on asphalt and concrete. I ran Rock ‘n’ Roll Half Marathon in WU3 comfortably, and since January this year, most of my running has been in WU4, except for 20 miler long runs (worn Kinvara 2). I am still debating whether WUs are good shoes to run a marathon for me. I plan to run Boston in Kinvara 2 but keep training in WUs and perhaps run a marathon in them later this year to see if they replace Kinvara 2 in marathon, too. I will share the experience here.

 

Born to Run Book Review

Born to RunI read Born to Run about two years ago and it had an economic impact on me: Since I finished the book, I have bought three pairs of Vibram Five Fingers – the funky-looking footwear with toes, which one of the characters in this book wears. I did run in them and liked how I felt; however, the novelty worn out as they became popular and more attractive minimalist shoes came on the market. Anyway, this is a book review, not a Vibram review, so I will try not to digress too much if I can help.

The author, Christopher McDougall, touches on a few interesting topics in this book and seems to have done a range of interesting research, from anthropology, physiology, human revolution, ultramarathon races, and shoe business. However, the meat of this book, at least to me, is Chapter 25 when he describes about barefoot running and its benefits. Whether his and barefoot proponents’ theory about barefoot running is true or not in this modern world paved with asphalt and concrete covered with pieces of glass and rocks, among other hazardous materials to your feet, it caught my curiosity and hit my weakness about running shoes. So I bought two pairs of Vibram Five Fingers. While I ran in them, or wore them in the gym, I did not develop any injuries. When they came out with a new model ‘specifically designed for running’, I bought the new model. I took them to city streets and track. They felt great and my performance improved, though I cannot give too much credit to the shoes alone, because my training has become tougher and I did wear other shoes as well.

The author’s arguments make sense to me. We all, at least us runners, heard one argument: Cavemen did not have shoes and they did fine without them. While such argument is not very convincing, the author sites a few convincing research results and interviews with podiatrists and specialists. The trend where the foot and knee injuries among Americans have increased since shoe manufacturers started to sell cushy shoes in the 70s seem not just a coincident. No modern medical technologies or alternative exercises have reversed this trend. The human feet are designed to absorb impact. If you protect them too much, it loses such functionality and starts causing problems, not only to feet themselves but also to other parts of the body.

Whether barefoot/minimalist running is just a fad or here to stay, this book is a very entertaining read, and it goes pretty fast. I would think non-runners will also enjoy the book for its colorful characters, anthropological aspects, and a setting where this non-fiction takes place. I recommend this book.

Mizuno Wave Universe 3 Review

Mizuno Wave Universe 3When it comes to running shoes, I have a hard time convincing me I don’t need any more running shoes. Very true that I have several shoes that are still in a good condition. While marketers say life of typical running shoes is about 350 miles, one can run in them after well over 350 miles and I still run in shoes that have more than 35o miles on them. But, it is also true that I want to find the best running shoes for different purposes; marathon race, track race, and regular trainer. No one pair of running shoes can fulfill all these purposes. Also, I run over 1,300 miles/year. In addition, new technologies are constantly developed, which may help run faster without incurring any injuries; therefore, it is not surprising that I seem to be buying running shoes all the time. So my running shoe purchases are well justified, and it only makes sense I know what are the hot running shoes and why (Wow, that was pretty convincing, wasn’t it?).

Mizuno Wave Universe 3 side viewSo, this is my first running shoe review in writing. I chose to write about Mizuno Wave Universe 3 that arrived on Dec 7, 2010. Yes, it is in pink-ish color, and no, it does not look like there is much cushioning or foot support, but this pair of shoes only weigh 3.8oz each shoe! This super light-weight-ness was enough to twist my both arms and made me frantically look online to get a pair as soon as I could. Waiting until after Christmas was not acceptable in case all others might have wanted them for their Christmas. Also, I have had many good lucks with Mizuno shoes. I wore Wave Rider 13 for over 500 miles. When I played volleyball, I often had Mizuno shoes. So, I totally trust the brand and its high-quality shoe manufacture-ability.

From this light weight, this is definitely a racer or racing flat, not a trainer. As you can see in the photo to the right, the sole is pretty thin and flat. There is only 5mm difference between heel and forefoot, which is thought to be good for runners who want to strike ground with midfoot or forefoot. I have not had professional assessement on the foot strike, but I am a mid-foot striker, so this pair may help with forefoot strike. However, because of this flat and thin sole, I would not run a marathon in them any time soon. I should be able to run 5K and 10K road races and track races.

I have not put a lot of miles in these yet since I bought them. Partly because I was recovering from CIM when these babies arrived and soon after I started to train for Boston. Another reason was that I bought Saucony Kinvara that I love so much. I trained and ran Boston in them. They are perfect trainer/marathon shoes for me. And honestly, I love Kinvara so much, I totally forgot about Wave Universe 3… What prompted me about Wave Universe 3 was Pride Run 10K results and how I felt about the race. After the race, I did not think to blame Kinvara for not making a PR. But when I look back now, Wave Universe 3 would have been a better choice for racing on gravel surface for a shorter distance, such as 10K. Kinvara is good when speed is not required, but when I want to race at faster pace, Wave Universe 3 would perform better. So, I will be running World Masters 5,000m in Wave Universe 3 this Saturday.

OK, back to shoe review. Other than the weight and brand that sold me this pair, these shoes fit my feet like a pair of socks, comfortably. There is just about enough space for my toes and they hug my wide feet so nicely that I don’t feel any tightness after I lace them up. I have three pairs of Vibram Five Fingers and they are comfortable, too. But I rank Wave Universe 3 higher in comfort. This is maybe from the fact that I don’t wear socks with Five Fingers. But I do want to wear socks when I run, because my feet sweat. Or maybe, my toes get uncomfortable in each toe compartment with Five Fingers. Rear side of the shoe (topline collar) has good support and is high enough that it does not feel like shoes will come off while I am running. The height does not bother or hurt my Achilles. The only discomfort is that my heel gets tired or sore after a while, and this is probably me not have got used to wearing  and running in them. Jury is still out on this.

Running performance with Wave Universe 3 is somewhat similar to that with Five Fingers Bikila, except Wave Universe 3 gives you more foot support and you don’t have to worry too much about not stepping on a rock or running in a pothole. Running gait seems unchanged with Wave Universe 3, too, while Five Fingers totally made me run differently. On a track race, I think Wave Universe 3 would give an advantage over other shoes, including Five Fingers, because my running form will stay the same and will have the same performance advantage of having little between your feet and track surface, and perhaps hitting the track with my forefoot more.

In conclusion, I really like Wave Universe 3 and would recommend to those who participate in similar running events to mine, unless they are just starting to run or their feet are super narrow. These shoes require feet and legs that have a certain level of mileage on them. Hasting into these shoes will only increase a chance of getting injured. I will go to the track practice this Thursday and run in them before the Saturday race. But I doubt I would change my mind on this at the last minute. Otherwise, my review has to be reversed and no one will trust my review in the future!
