One of the lesser-known adidas shoes to utilize the Torsion System was the Torsion TRDC. Appearing towards the turn of the millennium, the rugged runner was tooled up to offer optimum performance for the trail. The Torsion System was accompanied by a host of other functional design and fabrication qualities including an aggressive outsole pattern that provided superior tread, while the mixed-material uppers ensured comfort and stability. All this was wrapped up in a distinctive, of-its-era use of bright colors. STYLE#:EE7999
