Lighter, softer, more supple shoes can be sized closer to your measured size. Note: SCARPA Plastic mountain boots all use UK sizing; UK converts easily: 1 full size smaller than US men's size, 2 sizes smaller than US women's size. Try on with appropriate socks for your usage. The bigger the boot, the more appropriate a bigger sock. If you use orthotics or already have aftermarket footbeds, measure against the standard footbed in boot. Fit into boot for sizing/fitting the boot. Best to try on at the end of the day when your feet are larger/swollen, than when your feet are fresh to ensure good fit after a long day. Lacing can play an incredibly important part of a good fit. Be sure to play with lacing when analyzing fit. Make sure your heel isn't slipping. Make sure your toes aren't hitting the end. Approach shoes may be sized smaller for performance purposes but beware... small shoes are really uncomfortable on the trail. Scarpa Delta Men's Leather Gore-Tex Extended Hiking / Trekking Boot
