Normally size 11 1/2 and these are just too small
Size: 11, Color: Grey
They are cool and comfortable however I’m just in between sizes. My toes tend to jam into them, but I still wear them and they look great

This is never emailed
We have never received this warranty after asking multiple times and it is impossible to connect with seller directly. I highly recommend not buying the watch or the warranty. We only purchased the watch because of this warranty coverage. I suspect that the warranty is invalid anyway if anyone does get it emailed to them. So we buy the watch with warranty, it never comes so we just ask for a refund on the warranty payment but we keep the watch which probably dies within two or three years and because it’s not from the Fossil company we can’t do anything about it breaking down so soon. My guess is that’s the plan. Very disappointed and will not use this seller again.
