UA Threadborne Fortis 3 Sapphire is a high-performance shoe designed for a superior running experience.
The threaded embroidered upper provides breathability, structure, support, and directional strength.
The internal ankle bootie offers a snug and supportive fit for added comfort.
The molded Charged Cushioning® sockliner forms to the foot for a personalized fit and unrivaled comfort.
The dual-layer Charged Cushioning® midsole utilizes compression molded foam to enhance responsiveness, durability, cushioning, and energy return.
The multi-surface traction outsole pattern is engineered to grip any surface, ensuring stability and traction.
Anatomically placed flex grooves offer proper flexibility in key areas, allowing for natural movement.
Thanks to an all-new embroidered upper construction—and our obsession with each and every thread of fabric—we were able to design this shoe layer by layer for a fine-tuned fit that flexes and supports your foot, stride after stride.
