Bests & Worsts Reviews from Amazon

Love love love. Very comfortable and swishy. No straps sliding down. Nice snug fit. I wear a 9-9.5 so I ordered a 10. Have about 1/4 inch extra front and back. Ordering a different color now. Maybe the issue with the reviews saying the strap is falling down is relating to the shoe being too big, or wearing them wrong. I added a pic of the instructions. I can't see how that could happen otherwise. There definitely should not be a strap under the shoe.
