Hi all, I am so happy to find this forum! I recently started going to Zumba, and I love it, but I need to find good shoes. I got asics, but I had a terrible problem: while I was exercising, the temperature inside of my shoe must have gotten up to 100F. I had to return those shoes. Now I got Ryka, and I have the same problem. I still do not know how comfortable this pair is for me since I've worn them once, but the same problem appeared: as I was dancing, the temperature inside of my shoes increased tremendously, and I was very uncomfortable. I have an old pair of sneakers, which are not good for Zumba classes because they do not support my feet well, but when I dance Zumba with them, I do not have this problem at all. When I wore the Asics and the Ryka as well as the old sneakers, I wear all of them with socks. If the socks were the problem, then it's strange because (1) i can't imagine not wearing socks with sneakers and (2) I did not have the problem of the temperature rising with the old sneakers. I am really hoping that someone here would give me a clue about what to do, because I feel discouraged that I won't have a way to resolve this problem. Thanks!
