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.

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??
