Bought a second pair and the same thing happened after 7 months. 5 - I was nervous because my class was starting in a few days and I would have no time to exchange themFor me, the half size larger than normal was PERFECT. Sensor is a tiny bit iffy. Seed beads are fabulous. Set up is easy! I?ll do myself a favor and just buy this from Target or Best Buy to avoid getting scammed here. The characters are all very shallow and generally stereotypes. Bought these for my son in law for his birthday, he is happy, just got a miserable face. The rubber materiel is of a very high quality and I expect to get a few years of regular use out of themThe inside upper sole has a dimpled surface that makes contact with the foot promoting circulation and stops the foot from sliding. while i am totally confident in myself and my ability to ride mountain bikes i did have one time when i was stopped, then turned the front wheel to go into a part on a sidewalk, then on a fluke the wheel stuck wrong, the bike went over in a split second and by sons head barley touched the sidewalk, but he had a helmet on which slightly bumped.
