Shoes rub above heel and make blisters. These sandals are cute and have great support. 29, the slippers are made very well and the only issue I have was my toes are against the tip and I would have liked just a little more room. After doing some recording, it dawned on me that i was using low quality MIC and patch cables from the pre-amp to the sound card. Ok so Im an avid runner and have been for several years now. Anyways, buy them. How easy it makes songs change volume etc. The color and quality are fabulous. If youre looking for a lightweight black and off-white sandal these might be fine for you. Love them
