Beautiful, but doesn’t last
Color: 9910: All black
It’s beautiful, but does not last. Purchased as a gift for my husband and it stopped working altogether and wasn’t able to be wound after a few weeks. We returned it. He really missed having it so we ordered a new one, hoping to have better luck. This one lasted a few months but the needle for then”Day of the week” has since fallen off today. Very disappointing.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!
