Five Ten Aleon
Bouldering, cave climbing, gym steeps
Our tester wore a half- size down from his street shoe ( he usually wears his SS size in Five Tens).
Asymmetrical, downturned last; Adidas Primeknit welded w/ microfiber uppers; single Velcro strap closure; laser-etched heel; 0.1mm Bontex composite midsole; 4mm C4 sole
These Fred Nicole–designed shoes offer refinements our tester found exceptional. “These shoes are perfect for bouldering and steep sport,” he said after punishing them in RMNP. The Aleon shone especially for heel- and toe- hooking, with minimal dead air in the new, laser-etched heel.
