Due to my neck injury, I am unable to use a regular desk phone for our office meetings. the material on the top layer makes me feel like im walking on clouds. Could easily run to the store, etc. 5 (US) and the size 11 fits perfectly. Did I mention these are SUPER soft on the inside?? The outside is also soft! I just had to many shoes in the closet so I needed a under bed storage solution and this was the largest for the best price. Does not look or feel cheap and is able to support a reasonable number of clothes. Thought I had to buy a new set of headphones and when I stumbled on these, gave them a try. I looked all over for something that wraps around/stays put when moving, is small/light, is blue-tooth AND has both microphone and headphone (I need both to communicate with older adults and kids). (this is the only one you can get from a trusted brand)If you get this keyboard, I promise you that you wont be looking for an alternative in near future.
