I purchased these for my wife as she wanted shoes for walking that would (as Skechers claims)help her her tone-up. Because of the odd shaped sole, my wife fell while wearing these shoes and hit her head on the pavement. She received a concussion and required 2 stitches.  The nurse at the hospital informed us that these shoes have caused many injuries and there is a class action lawsuit against Skechers because of the numerous injuries caused by these shoes.  Buyer beware! These are unsafe and dangerous shoes to wear.
