Love these, so comfy!
I absolutely love these shoes! I got them a couple years ago in the sand/ light brown and fell in love with them. They are so comfortable, sizing is accurate, and material is high quality. These quickly became my go to shoes for both house shoes/ slippers to running errands. I knew I needed to get another color and absolutely love the black! They are so cute and stylish; almost like a cross between Tim’s and Uggs. Highly recommend! They are so comfortable and versatile, you’ll be so happy you have them!

    Too stiff & now by time I figured it out. I missed the cut off date by a week to return them, which is very upsetting to me because I’ve only wore them once in the house an hour and by time I took them off my feet were swollen and they hurt really bad but over a few days I can’t return them. That’s very frustrating

    I'm a hockey Mom. I spend my life at the rink. I can't stand when my feet get cold. I have tried everything! It's been an ongoing battle to find something to keep my feet warm. I saw these and figured I would give it a go. It's a MIRACLE! My feet are toasty warm! One time my feet actually started to sweat. I know that sounds gross, but my feet were warm. They look cute with leggings and jeans and they are easy to get on and off. I just took these to Pittsburgh. I wore these all weekend (and it snowed). Never had a problem. They are a lifesaver for my toes. My only issue is, they are wide at the front --- makes your feet look kinda big. But who cares! My feet are warm.
