The welding holding the Velcro on did not hold up and came off completely on each end, it also began coming off on the middle piece as well. If you have a wide foot, be warned! I haven’t had them for long, but they are holding up pretty well. Assembly took about 2 hrs - not all of the pieces were labelled, but it didnt affect us that much since we followed the instructions and could see which parts were needed. When it’s cold outside I would be wary of the rubber tie downs cracking or snapping if pulled too tight. Ive had lots of Bluetooth devices and pairing has never been an issue. A small is more like a 5/6. ( my feet do not over or under pronate) They were cheap and cheaply made. It tends to cut out very often. There’s nothing wrong with this thing’s mounting plates.
