I really like these shoes. I’ve been able to wear them for about a week now and am really impressed with how they’re holding up. A lot of my shoes start to squeak in a similar amount of time and these still feel like they just came out of the box. I especially like the heal support, it feels like it’s really gripping the heal nicely My one complaint is that they seem physically larger than most size 11 shoes from Nike I buy. In spite of fitting the same inside, the actual shoe seems about an inch longer than my other Nike size 11s. It’s not a deal breaker and it doesn’t impact the comfort, it might even make them more comfortable, but they look a bit large on my foot. And if you have a narrow foot, you might be swimming in these.

Can’t Miss Shoe

Size: 11, Color: White/Blue Crystal/Total Orange, Size: 11, Color: White/Blue Crystal/Total Orange

Great looking shoe! Fit to form, I wear a size 101/2 or 11 and I ordered a size 11 and they fit perfectly. Soft and comfortable perfect for walking as I suffer from knee and back pain at 59 years old…. Don’t judge me. Normal width size for me so not sure about the wide fit but the toe room for me is comfortable. Great choice will definitely recommend.

Yes Go Nike!

These Nike men's shoes are very comfortable. It's a pretty versatile shoe. I am able to work out in the gym, go for hikes, walk on the street and run errands all with ease and comfortability. They are sturdy, have good cushion and great support for your joints and back keeping you aligned. They lean on the more narrow side for fit so if you have wide feet they may not work for you. The green around the heal is attractive. The price I paid for the shoes was extremely reasonable making them a great value. I have been using them for a couple of months now and they are still in great shape. Excellent buy!
