Size Up!
Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate, Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate
These are very comfortable! My only issue is that I'm a size 9, so I ordered the womens 9-10 and they are *almost* too small. My heel really wants to come out the back. I know the description says to size up, so you really should lol. They are also narrow, as I have wide feet! I will still wear them, just not if I have to walk too much

No more stubbed toes!
This is a very comfortable slip on shower sandal. The bowl design that makes it protect your toes and feet works like a champ! No more stubed toes !! They wore great to prevent that. And they have great traction in smooth wet surfaces. Even with soap on them. Comfortable fit.. I would buy this product again. Thanks

Size up
Size: 7.5-8.5 Women/6-7 Men, Color: Black
I had another pair of a different style from the same seller that shrunk when left in the sun. That one wasn't available anymore, so I bought this one in the same size, and they are too small. They are comfy shoes but not true to size

Perfect for after knee surgery
Size: 7.5-8.5 Women/6-7 Men, Color: Blush
I ordered these after having knee surgery and they’ve been a god send. I wear them around the house and they help so much with knee pain. They’re great quality and sized as expected.
