So comfortable!!
Size: 11, Color: Champagne Metallic
Love love love!! Great fit and work for wide-ish feet. Run a little big. Took me a couple days to break them in but now they are great. I bought a second color!!

VERY comfortable & cute sandal!
Size: 9, Color: Cognac
I needed a pair of comfortable sandals for this summer & I really got lucky with these. I have a lot of arthritis in my feet & even my $100(+) tennis shoes don’t keep the pain away. I may start with tennis shoes at the beginning of the day but 1/2 way through I slip on the Hey Dudes & all is much better!
These sandals are versatile, I have worn them with jeans & shorts. They would also look nice with a skirt. They are cute & comfortable! Not only are they lightweight, it feels like you are walking on air because the sole is so cushioned.
One thing I do want to mention is the fact there is A LOT of room given toward the front of the shoe. The strap that goes over the ball of your foot is looser than I am used to, even with wide feet. You aren’t able to make adjustments. When I first put them on I didn’t think I would like it but after wearing them every day for the past month I know I do.
I would recommend these sandals & wonder if I should stock up in case they stop making this style??

Cushy softness
Size: 8, Color: Ivory
I’m normally a 7W and originally ordered the 7 and it was almost a perfect fit if not for my high instep. Exchanged for an 8 and they fit great just a little loose in the toe strap but I can make it work.

Ripping with minimal wear.
Size: 8, Color: Black/Black, Size: 8, Color: Black/Black
I really wanted to love these. This is my first pair of HeyDudes, and I am pretty disappointed. I don't have wide feet. They fit perfectly, and were super comfortable. But they are already ripping and I haven't even worn them 5 times. I didn't even wear them long or walk a lot in them.
