Ortholite, a brand of insoles, has a good reputation in the footwear industry.

Note: Different insoles don't have to worry about whether the shoes are genuine or not, as long as they are products purchased by official authorized stores.

The origin of Stan Smith;

This pair of shoes was originally designed in 1963. Originally, it was not called StanSmith, because these shoes were originally designed for a famous French tennis player named "RobertHaillet" at the Davis Cup in France at that time.

This kind of shoes were not very special at that time, but were sold as ordinary shoes. However, it is said that a very important person once bought this pair of shoes. This man's name is Robert Louis Dreyfus. He is a Frenchman and he likes them very much.

This man later became the head of Adidas, and it was he who bought Adidas in the early 1990s and saved Adidas from the darkness in the early 1990s. However, signing Stan Smith really has nothing to do with him.
