The Street LV Climbing Shoe is a lower volume option based on on of So Ill's most aggressive, downturned shoe for the gym's hardest boulders and routes. An ultra-thin midsole gives this shoe superior softness for feeling the smallest jibs on the wall. Its Dark Matter rubber comes from So Ill's UnParallel Rubber family, which the Navy Seals use for reliable traction during covert missions, and its non-marking convenience ensures long-lasting durability. The synthetic upper has a padded tongue for comfort, and since it doesn't stretch much, So Ill recommends sizing the shoe similarly to your regular street shoe.
