The test pair of Xero Shoes Prio arrived a few hours before I flew out to compete in the Bermuda Triple Challenge, so I did what any logical person would do; unpacked my other "race" shoes and decided Xero Shoes were the only ones I'd bring on vacation for 10 days, compete in 3 races, and even cliff-jumping. Did these lightweight, flexible, zero-drop minimalist shoes have it in them to hold up to Bermuda Triple Challenge?
