The sleek Threadborne Fortis 3 can accompany you on daily runs as well as more casual outings. It weighs 9.45 ounces, meaning it's lighter than both the Speedform Gemini 3 and the Threadborne Slingflex. Despite its lightweight design, it has a dual-layer of Charged Cushioning in the midsole for a high degree of comfort. The internal ankle bootie helps secure your foot against all that cushioning. The Threadborne embroidered upper is constructed to give you support without limiting breathability.
