La Sportiva Trail Running Shoes

Go 0.5 size UP from your daily street shoe size. This extra space prevents your toes from smashing into the front casing on fast, steep downhills, which causes black toenails.

La Sportiva Trekking & Hiking Footwear

Go 0.5 to 1.0 full size UP from your daily street shoe size. Carrying a heavy backpack forces your arches to flatten out and expand, making your feet physically wider and longer under load.
