  • Very Comfortable.
Size: 10.5 Color: Black
These took a while to arrive but I love them, they fit a little big but are incredibly comfortable. I have tried a number of other boots and like these the most. I have not crashed in them yet so I can't speak to how they hold up and protect in a crash.

  • Exactly what I wanted
Size: 6.5 Color: Black/White
The product is as described, fits perfectly, very comfortable, good boot once broken in! Would definitely recommend and buy again

  • Love these boots!
Size: 8 Color: Black/Black
These boots are great! Offer tons of protection, comfortable, fit true to size and love the style. They were a bit on the pricier side, but I think it’s a good investment, especially when it comes to protecting your body and skin!

  • Good Motorcycle Boots
Size: 10.5 Color: Black
Bought these for my boyfriends, he was looking for boots to go with his motorcycle. He found them to be comfortable, sturdy, and sleek. He's a size 12 and they fit his feet perfectly.

  • Protection is worth the price
Size: 9 Women/9 Men Color: Black/White
Def enjoying my purchase! You will have to break them in but it doesn’t take long. Still able to shift gears with no issue just took a little getting use to after riding in sneakers for a while. A lot of protection and they look great with the rest of my gear. They have a zipper along the ankle to mid calf area then cover with a Velcro flap to hide the zipper. Glad I spent the money as it was very much worth it. ... show more

  • Good beginner boot
Size: 13.5 Color: Black/White
These boots are great and I ordered a half size up, my only concern is the longevity of the Velcro.
