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.

I will wear these all summer!
Size: 8, Color: Black/Black
These sandals are definitely a platform if you’re looking for a bit of height but they’re also well made, comfortable and in my opinion much firmer support than another popular brand. They look great and they’re versatile. I purchased the black ones the color is a true deep black not gray-ish at all.
