I would be nervous of a stitch grabbing the liner and causing some kind of issue. Brilliant quality duffel bag for travel and gym purposes! Unfortunately, these BearPaw slippers wore thin on the insole in a couple of months. Not quite tall enough or wide enough to hold a regular sized bath towel. Theres also enough room under the bottom shelf for boot boxes or another row of flats/tennis shoes. What started out as a normal, comfortable shoe somehow turned into a shoe you have to wedge on. One disappointed daughter waiting in the mist of the coronavirus Panademic for these thrives to take money but not give anything but a empty box! I have the cheaper sorts but theyre not as good. Its strange because I do notice that they block out noise much better than the silicone tips which would lead me to believe that they should noticeably improve the volume but I just didnt see that in my very simple testing. amazing.
