Nike basketball shoes have many inner boots. For example, in this year's flying club, Kobe's previous pairs of shoes used huarache technology, not inner boots technology, and they were very comfortable without socks. The inner boots are actually equivalent to a layer of socks, only connected with sneakers. You can understand it this way: a pair of shoes is actually two pairs, one is the outer part, such as the outsole, and the other is the inner boots. Here is a picture of the Flying Club, which is Parker's signature shoes. In addition, Nike's "Bird's Nest" casual shoes launched at the Beijing Olympic Games also have inner boots, which are cool and suitable for barefoot wear.
