This is the first "Real" tennis shoe I've ever had. I'm a 4.5 player but never truly invested in quality equipment other than my racket and strings. I got used to playing with ASICS running shoes and an ankle wrap for extra support, but with these shoes, there's no need for the ankle wrap anymore. Great side support and amazing speed. Even though these are slightly heavier than my previous shoes, I feel like I'm reaching balls that were previously impossible to get.Most ASICS shoes fit me perfectly in 9.5, but this one is a little tighter on the sides, but that is to be expected, as it's tight in all the right places to bring extra support.Great traction on hard courts. Haven't tested them on clay yet.Took me around 20 minutes of playtime to get comfortable and break them in, the hard plasticky cover on the top was hurting my big toes when running, but that discomfort quickly faded away as I played.Overall, great tennis shoe, I didn't know it would feel so different, in a positive way, I'm reaching more shots and have more confidence on the court. Will definitely buy a second pair soon!Bought these for my son. He’s worn them for practices for about 3 weeks now, and says they feel great.I did have to order a half size up, as his normal size was too snug. Also, he was wearing sole inserts to help with plantar fasciitis, but hasn’t had any flare ups with these shoes. Excellent cushioning & support out of the box!I wear size 10 but I bought 10.5 and it fits really well. Extremely comfortable and I broke in right away.The old adage 'if you find a shoe that fits, stick with' it couldn't be more applicable. Acics running shoes and tennis shoes fit consistently across their line. This shoe is light, flexible and comfortable right out of the box.I have been wearing ASICS size 10 for years but this time I followed other purchasers' comments and ordered size 10 1/2, I am glad I did that.The only shoe that survives my son’s 5 hours of training each day!!! Each shoe is good for a month!Sneaker works great on hard servace. Very supportiveBest tennis shoesThis is definitely better than the previous version. It’s as light as a running shoe and has no heel slippage. I also find it sufficiently cushioned in the heel and midsole.It allows to me to move around the court quickly.If you're looking for great tennis shoes, - look no more, - this is the one! Very comfortable and really nice looking!.It's just what I need for tennis play. Fit well and quit comfortable!Haven’t had a new tennis shoe in years, but used to play a lot and wanted performance. This was super light, lots of lateral control, comfortable, and fit like a glove to my expected size. Expensive, and worth every penny!Fantastic shoes. Light and great support for tennis.
