Ive had a pair of Birkies for three years, worn outdoors in the summer and indoors all year round and have found them extremely comfortable (the footbed moulds to the shape of your foot) and warm in winter - in fact warmer than fur lined slippers! We got them for a Colorado hiking trip and a beach trip shortly thereafter and they were wonderful. However, I am interested if someone does know of the perfect bar bag--room for the XR and narrow enough to not make knee contact, but still roomy enough for snacks, gels, map, etc. I also have orthotics in them so those take up space. So if you have a big butt like me and you want to look smooth and snatched in the waist without losing the jiggle of your booty as other Shapers would do buy this product. I didn?t realize it was transparent and was concerned that my black phone wouldn?t show the design. That is, until yesterday. The BT remote immediately paired with my iPhone X and I was taking tripod selfies with my dog in minutes. So while I recommend the sandals themselves (but buy a size LARGER than you?d expect) I highly advise against buying from Peltz Shoes. I have an update: These slippers are so loose now that I cant keep them on my feet.
