Only one negative: the strap on the left sandal was too tight at first and dug into my foot a little. Fortunately it has stretched enough that it's comfortable now. I really like these sandals because they have a snug fit instead of being loose like most other flip flops I've had. My feet are really narrow, but don't slide around in these sandals because of the way the footbeds are molded. The sandals are well made, rugged and sturdy, so I think they'll last quite a while. The traction on the soles is a real plus since I walk on rough terrain frequently.
