My current strap is around 33-34 inches at the shortest, and I'd like something that goes even shorter than that, perhaps 30", but so far, the shortest I've found are the Comfort Strapps, which only go down to 33". Does anyone know if such short straps are sold anywhere? I've also read about people sending their straps to a shoe shop or something to get it shortened. If I go that route, which straps are recommended? Thanks.
