Adidas UB20 also has a pair, but the upper edge of the tongue will not fold inward after running.

There are several possibilities for this to happen:

1. Your shoelaces are not tied properly, resulting in too loose shoes and a crooked tongue.

2. The socks you are wearing now are not suitable for wearing this pair of shoes, or socks with slippery material and high polyester fiber content.

Your shoes are too big, or your feet are too thin.

These shoes don't fit your feet.
