If the sole was not slick I could give these a five star: the shoe upper is a gently metallic woven webbing that I'm guessing would be cool and very durable. It flexes to meet the contour if the foot so is comfy. There is no arch support but I was able to easily insert an orthotic. The problem is the very slippery sole. I will be returning because it makes them hard to walk in on flat smooth surfaces.
