I usually wear an 8 1/2 in other shoes but for the Crocs room fit shoes a 6M/8W fit great. One (out of 4) can hardly move at all. Sound:This wking X10 comes with 2 sound modes indoor (bass heavy) and Outdoor (poor Bass and not even Louder than the indoor Just a bit more emphasis on the highs). The insole can be removed and replaced with an orthodic. Was fairly easy to set up, seems to be durable enough to hold my shoes, and I was able to stack a board on top of the rack to hold either an extra pair of shoes or other things like in my imageIf you have a small amount of shoes with not a lot of space to put a wider rack then this is the shoe rack for you. The silicone bands are surprisingly good at keeping the phone from falling out and down but the mount does not hold its place well. I will be very up front and say that the foam (like with most memory foam slippers) goes flat relatively soon and I usually see small tears in the fabric after a few months but to be fair, I wear them constantly. Also super adorable! I recall many of the reviews I read stating that your device did not affect the volume so I was really disappointed in the output of this speaker. I ended up returning the order and ordering from a different vendor.
