The Boreal Mutant Climbing Shoe is a great option for expert climbers who want a do-it-all shoe for bouldering and hard outdoor routes. With an asymmetrical downturn, curled toe profile, and grippy rubber, this construction may not suit beginners – but it will provide the security and performance needed for advanced climbing.
