Alpinestars Supertech R motorcycle racing boots. Top of their line boots. Buy once - Cry once. US men’s size 10. Euro size 43. I ordered these on line and wore them a couple times and thought they fit great. Then I tried on the next smaller size at Cycle gear and they fit a lot tighter/better so I bought the exact same boots in the next smaller size since I love these boots. So I cried twice on these. Hahaha! For example I wear a size 10 in vans or Adidas and a euro 43 in Sidi motorcross boots. Only used on a couple mountain rides recently. Asking $400 or your best offer? Thanks
