That's it really. DS does have a sensitive sense of touch, along with malformed feet (extra metatarsal means his rt foot is esp. wide at the base of toes, so sock seam just catches him there).
Can't turn socks inside out, esp on school days. He gets teased (bullied) for having funny feet as it is. No way will he wear inside out socks to add to the bullying factor (even tho a few years ago he always chose to wear them inside out).
