Bought for sports, needed a soft comfortable sole. These air-filled soles are perfect for traction and running. The tops are soft and flexible, you have to take them down a bit for all sports and fast movements, but they are durable and well made. There is no specific brand so I was happy with the material used. I chose a size based on my men's shoes. So if you are a woman I suggest going down a half size as my exact mens size turned out to be too big for me. So I'm glad there are half sizes! The bottom isn't foam like I thought it would be, but the buoyancy of the outsole makes up for it with support and a very light weight. I like good prices!
