I work for the USPS and Im on my feet 10 hours per day, 6 days per week, 52 weeks per year. Maybe in a different material or with some type of lining on the canvas would make this a more comfortable slipper. my fav groot 😍 I dont know about you, but I expect a "certified refurbished" iPad to last longer than a 90 day warranty. This is a very sturdy case. También lo que ayuda a que la batería dure mas es que el teclado el minuto que no tiene algún presión de tecla, este se apaga y cuando presionas cualquier tecla se reactiva muy rápidamente. I got these today, just in time for a two hour Zoom conference call. If I wore them without socks I think theyd really be too big. So after going through 4 pairs of these. Took a while to figure out how to adjust them on feet but once that was figured out they fit very well.
