I worn these with socks and without socks both very comfortable with the memory foam soul. If you dont tighten them at exactly the same rate and keep them even, you might pop off a nut trying to tighten one side with shorter threads, and screw up the threads on the shorter side. This is most unfortunate and did cost me a pretty penny for the back and forth shipping. My granddaughter loved the slipper but they were a bit too large. I didnt get a lot of ambient room noise, just what was directly in front of the mic (and a little of the computer fans from behind me). There is a little wind noise once you reach 40 mph, but nothing terrible. Depende de géneros y gustos en si. I?m a delivery Capt and got this for a delivery with ?the admiral?. Also removed the loop on the heel strap as it was unnecessary. Very heavy duty.
