Standard footwear uppers lack targeted support and protection in high-stress zones like the forefoot and instep. Addressing these structural deficits prevents premature material failure and improves foot containment during dynamic movement.

Weak mechanical adhesion between heterogeneous textile and sole materials. Improving interfacial integrity prevents delamination and structural failure during high-stress use.

Standard textile uppers lack the necessary directional stability and tensile strength to withstand high-stress athletic movements. Enhancing structural integrity through integrated elements prevents material over-extension and improves energy transfer.
