The Under Armour Spieth One, a collaboration between Under Armour and golf sensation Jordan Spieth, debuted on March 1, 2017. This marked a significant milestone, being Spieth's first signature golf shoe and only the second such release by a professional golfer at the time. The launch was a direct result of Under Armour's strategic partnership with Spieth, a deal that began when he was just 19 years old.
Engineered as a performance golf shoe, the Spieth One prioritizes stability and traction throughout the golf swing. It incorporates Rotational Resistance Traction (RRT) spikes, developed with Champ Spikes, including Zarma Tour and Zarma Tour RST styles. The Dual Durometer sole design offers a softer forefoot for flexibility and a firmer heel for enhanced stability. The shoe's lightweight EVA midsole and removable footbed provide responsive cushioning.
The Under Armour Spieth One achieved prominence through its association with Jordan Spieth, a globally recognized figure in professional golf. Spieth's presence, particularly during the Spieth One Global Tour launch across Tokyo, Seoul, Los Angeles, and Mexico City in January 2017, significantly amplified the shoe's visibility. Furthermore, Spieth's consistent use of the shoe in Professional Golf Tournaments at various golf courses worldwide throughout his career cemented its status.
The 'White Steel' variant features a streamlined, single-seam upper designed for an exceptional fit and feel. This construction incorporates UA Storm technology for waterproofing and breathability, ensuring performance in various conditions. The design includes perforations in the shape of Spieth's 'S' logo on the instep. The shoe utilizes materials such as microfiber (later Clarino®), and a waterproof membrane, contributing to its lightweight build.
