Why don't they make sandals or shoes for people with hyperhidrosis?

Most sandals or shoes that are meant to be worn without socks have insoles that don't absorb moisture - not to mention, these materials aren't very comfortable. I can't wear most of the sandals or thongs I see due to hyperhidrosis. I've seen very few open-toed shoes that have cloth or fabric insoles. Can anyone recommend a line of shoes (or specific pairs) that have absorbent/fabric/cloth/suede insoles?
