Summer sweat tips from the International Hyperhidrosis society. For foot sweat, I tried Summer Soles, and it seems to help a lot. I still haven't graduated to wearing sandals to work. Today it was 95 degrees out and I wore thick socks. According to the IHS article, temperatures inside socks and shoes can reach up to 120 degrees in the summer. I can believe it!
