The plastic is not as “clingy” as silicon, and doesn’t collect dust and lint as easily. These are probably only worth about $30, so this isnt a way to save money. They pair quickly every time. This doesn’t so it’s a thumbs up in my book. They are a Christmas gift, so dont know how they fit. This shoe was a hit. I got a size 7 and I have wide feet and to be honest my feet fits perfectly in these slippers. So I ordered this one and Amazon delivered the next day. I have returned these sandals. I have seen all kinds of awful things get rinsed out of my sinuses, including dog hairs and other allergens, and every time I use it, things just keep getting better.
