So I just got the Teeth shoes last night. Today I decided to use them to see how they feel. Immediately I found the shoes to be extremely uncomfortable the way the fit was. It also felt like a cheap knockoff. No substance and thin feeling. I didn't like them from the moment I put them on, but wore them anyways thinking they would feel better after being broken in. Used them for 3 hours 1 time only and this happened. The inserts ripped right out of the shoes. May I suggest not purchasing these if you are considering buying a pair? This is the 2nd time I've used a pair of Oakley shoes and they failed on first use. What a disappointment
