Great comfort, but not built for long-term daily use
Size: 9.5 X-Wide, Color: Black/White, Size: 9.5 X-Wide, Color: Black/White
I've had this shoe for almost a year now. I use it almost daily on a walking pad while working from home, plus as a gym shoe. After nearly a year of this routine, I've noticed considerable wear on the sole. Don't get me wrong: the shoe is great and very comfortable, looks decent, and fits great at the start, and has good breathability. However, that comfort has started to fade as the shoe has worn down. Gel-Contends 9 is a really good shoe, but definitely not a long-term, heavy-use shoe. Perfect for casual or rotation use, occasional runs, but don't expect it to last 12+ months of daily wear.

Bought for husband, he says that they feel comfortable have good cushion & feel stable while he runs. Give him traction on the beach running or on pavement! Sharp looking shoes!

Sold on ASICS for my running needs.
Size: 8, Color: Carrier Grey/Anzu
I run 40+ miles a week. These running shoes are terrific. Can afford the expensive brands/models and this fits my feet, price and running requirements. Have purchased several over the years.

Comfort and Great for Standing
Definitely the best shoe for standing on ur feet all day. I stand for about 7.5 hrs a day and this has changed things for me drastically. The foam makes a difference and the shoe is stylish as well.
