Very rare sneaker, I've never seen another pair and can find no info regarding them. Excellent condition for the age, they were New Old Stock when I purchased them and I only wore them several times. Some yellowed glue on the uppers and the vinyl ankles are flaking Wearable, flexible soles They are marked size 11 but they fit somewhat larger. I generally wear a size 12 sneaker and they fit me well, if not a bit snug Includes original thick cotton laces
