Physical limitations or situational constraints make traditional shoe donning and doffing difficult. Reducing the mechanical resistance of the heel and collar improves accessibility for users with limited mobility or those requiring hands-free operation.

Standard footwear closures often fail to provide independent tensioning for the medial and lateral sides of the foot. Addressing this prevents internal foot slippage and improves stability during lateral movements.

Standard footwear openings limit ease of entry and exit for the wearer. Improving throat and collar clearance reduces mechanical resistance during donning and doffing.
