Designed together with Parachuting Special Forces, the Pilgrim TSC DS is very lightweight and breathable, specifically suitable for hot and desert climates. The malleolus is protected on both sides by an integrated layer of Poron® Performance Material. Poron® is a dual-action solution to help alleviate the number of damaging shockwaves caused by strenuous activities and to absorb lateral impact. Other features are an anti-nail penetration insert in the insole, antistatic construction, and antistatic nitrile sole. Designed with features to meet the needs of demanding fast ropers. The internal side of the shoe has been reinforced and treated to withstand rope friction, and a higher-density EVA insert has been placed in the midsole to resist the heat generated by rope friction.
