Usually a 12 fits me perfectly, these are the tightest size 12 I've had. Soles of my feel go numb a bit on the elliptical. I would order a half size up if I were to place this order again.Not as comfortable as my other ASICS, but still great sneakers. This one runs small.It is hard for me to give them a rating because I was never able to use them. I tried them on but they were way too short and way too narrow. I’ve always worn size 13 ASICS but these size 13’s weren’t close to fitting. Unfortunately, I got stuck paying return shipping even though I bought the right size but ASICS built them the wrong size!UPDATE: THe quality of the tennis shoes wasnt good. The sole of the shoe came apart after only 50 miles on a treadmill. I have always used asics and its the first time I have this issue so it might be unfair to give the product a bad review, but I want to put this out there in case some other people have experienced the same thing. As always, Amazon customer service helped me solve the issue and gave me a full refund (prime member).Too much information is out there about running shoes. If you run about 20 miles per week and your long run is about 8 miles, this shoes are worth trying. The value they bring at under 40 dollars is hard to match: Light, decent cushioning, very comfortable and made for running.My husband teaches PE and absolutely loves these shoes! They are great for being on your feet all day. He has a narrow foot and these fit perfectly. The blue is very nice and works well to wear daily. Would def recommend this shoe.Advice given to me. These shoes are sized a bit small, recommended to order a half size bigger if you are flat footed and/or wide toed footed. Great quality shoes, using them inside and out of work they last me about three to four months. Well balanced athletic shoes.Style's good, if you're looking for a shoe that'll work for both the street and for running. But they are already falling apart after 6 months of training and wearing. Also, the fit is pretty narrow.This is a running show for my son, who is doing speed training (he's a catcher and wants to make sure he doesn't lose a step). He says these shoes are so light they're almost like wearing socks. Absolutely fantastic!As expected had these trainers beforeMy pair of shoes came and I was excited to put them on but found that they fit small. I wear them for work purposes and they are not bothering my feet like a too small workboot would. The exterior fabric of the shoe is, I said weak, but should maybe say delicate. The shoe scuffed a little on a concrete curb, I think, and not very hard. The shoe has a spot on it that the fabric is obviously not good anymore. I won't buy this style anymore and question if I will by this brand ever again.Buy it 1 size bigger than your normal size and it will fit perfectlyWas a bit tight when I first wore them. But after a few days with them, the fit is perfect.Fabric was not as expecter
