I've recently began taking Zumba and Cardio Funk classes at the Y and I've noticed that my feet hurt during some moves. In one routine I have to do over a minute of jumping jacks. Just two weeks ago I had a hard time completing them because I've been so inactive but just yesterday I had the endurance (woohoo!) but what stopped me from completing the 1 minute was the pain in my feet. It was like a sharp pain which makes me think that I need a good pair of shoes that are shock absorbent. Some times it happens when I go into a deep lunge, my thighs are burning, fine, but it's my feet that are killing me. I'd love some recommendations on a good pair of workout shoes!
