Ive been a size 9 in shoes for a long time, i dont know why an 11 didnt fit me. This ear bud case arrived broken. I have a pair of official hiking boots, but they hurt my feet. They arrived on time, in a nice woven fabric pouch. but they did, AND arrived a day early. At this point I could not get my Astro A40 mic to work properly and consistently, the sound was only marginally better than the M80 MixAmp and no mute cable included. I was ready to send them back, but Im so glad I gave these a chance to break in. I didn?t expect it to be as loud as it is. They seem to have the nice supportive footbed like their sandals, it is not cushy which is nice for me. If you are looking for something with a thick tough tread and sole then this slipper is not for you.
