5-11 shoe and these fit me perfectly. They have a comfortable, fully customizable velcro closure that allows for someone with a sensitive foot to adjust as needed. What Im more disappointed about is the lack of frequently used spices. I was using hdmi arc cable initially , after using amazon basics optical cable I didn?t find much of sound difference. I was able to attach the rails to my 2017 Highlander but they do not attach to both holes on the top. They are thick (which is good), so they are stiff. Very nice style and comfort for a flip flop, a little pricey, but not too expensive. I recommend that this product as added to anyones workout. ????????????????????????????? ?????????????????????????????????? ??????????????????! Rubberized grips, mechanical buttons, fits great in the hand, steel reinforced device holder, etc.
