I have been wearing this particular shoe brand for years now for my summer training sessions in Tai Chi Chuan. They are extremely flexible and soft, and it is no coincidence that they are among the top choices worldwide for those practicing Tai Chi and Kung Fu. However, they are not particularly durable, and with intense daily training, they have not lasted me more than 1 year, which is why I have bought several pairs. But considering the price, they are a very cost-effective purchase.
In terms of positives, they are soft and flexible, they do not slip, they are cool, and they come at a very good price.
As for negatives, they are not durable.
