Well made sandals
Nice sandal that works well for me, feet sit comfortably in the shoes. I’m a quadriplegic that needs someone to wrestle my legs while putting my shoes on for me. These go on fairly easily. I have short legs and the extra height of the sandals helps to reduce the pressure on the back of my legs while my feet are on the legrests. Also my ankles tend to buckle and cause my feet and shoes to roll over onto the side of my foot. The soles of the UGG Goldenglow are wide and flat, substantially reducing this tendency. As far as comfort and function while walking, I can’t speak to that.

So comfortable but only lasted 5 months…
Size: 9, Color: Sea Salt, Size: 9, Color: Sea Salt
I was hesitant to buy these without being able to try them on, but I’m so glad I did! They are incredibly comfortable. I am on my feet for a large portion of the day as a school principal and these feel amazing all day. They’re very adjustable so if you have feet that swell (or just fatter feet like me) these should be able to accommodate you. They are clunky but really cute! They’re also easy to clean. I’ve worn mine just about every day since I received them and can easily wipe them down with a wet paper towel to make them look new. They will occasionally trip you up if you’re not careful, the same way Ugg boots can do, but that hasn’t been a big problem for me. They’re very lightweight and versatile. Love them! Update: I probably just wore these too hard because today I was walking the school hallway and the shoe just snapped. One of the sides was completely unattached and within 30 minutes they were only on my foot by one strap. Super disappointed!! But I loved them enough that I ordered another pair to get me through until boot weather.

Great shoe, room for improvement
Size: 7, Color: Bison Brown
I wore these to a 2 day music festival and my feet were so comfortable dancing and walking all day. Got a little sore by the end of the night, but the only thing that would have been more comfortable would be athletic sneakers so that pretty good for such a cool looking sandal. Sizing is off tho. I am a 7-7.5, and I ordered a 7. Length wise theyre good, but maybe I have skinny feet because I had to strap the 3 Velcro straps as tight as they could go, especially the heel one. Maybe I would have been better going down a size because I want to have my feet feel super snug and secure in sandals, especially if I’m dancing. But overall great sandals and honestly I’d buy them again
