Its a great idea but just not good enough. I dont have to stop to adjust or fix it while Im working out. Cheap item Deep bass, clear separation, and not tinny. On my Bell we were not so fortunate. If there had been a choice I would have gotten a Junior size 3 for him instead. I order these shoes to big I didn?t know that were unisex until I got them which was way to big Sadly I had to return them Fantastic durability! Got the 8 and they are a tad long with a bit too much room in the toe box. My feet are painful, especially first thing in the morning and these slippers are heaven!
