This is a nice sneaker, but they focused too much on the memory foam and forgot about the rest of the shoe, Memory foam is cool, feels good, good ventilation even on HOT days, but I find the actual foot support lacking, the arch and lateral support is very weak, the sole shock absorbency of the shoe is almost non existent, but this is masked by the memory foam, if not for the memory foam this would be a very hard shoe for walking, And like its name Flex Advantage, its too flexible, and that's why I say no lateral or arch support, the sole seems very weak and low quality, probably wont last long. It is a comfortable shoe, but I would not purchase again.
