These boots fit perfectly, as reviews elsewhere state they run about one size big. In most shoes and Alpinestars Tech 10 boots I wear a 14. The largest the Scout comes in is a 13, but they fit perfectly. The only issue I had was the center buckle was vastly too short . I called Alpinestars here in the USA and they sent me out new buckles that arrived in 2 days free of charge. I would need to more time to test durability fully, but I gave them a 5 based on construction and experience with Alpinestars products. They have good feel for the controls and they felt broke in almost immediately.
