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.

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely. Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new. For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again

Stylish and inexpensive
Color: Grey
Great watch. Came in quickly from seller. Got it sized at a local shop. It’s a pretty stylish watch for the price point. I don’t have big wrists but I still think the face could be a little bigger. But it’s pretty sleek and I’m happy
