The Under Armour TriBase Reign 3 ‘Halo Grey’ delivers a neutral colorway of a lightweight training shoe built low to the ground and with comfortable bootie-style construction. Light grey engineered mesh is utilized on the upper, fortified with tonal no-sew overlays and a molded external heel counter for improved support. Responsive cushioning arrives via a full-length Micro G foam midsole, reinforced underfoot by a durable rubber outsole that wraps up the lateral sidewall for added traction.
