Pairing a seamless, closed mesh upper with a full-length Fastglass spike plate, the Sonic Sprint (Rio) gets you ready and raring to speed to the finish line. While the plate provides optimal torsional rigidity, the upper prevents debris from entering the shoe. Finished with a collar lining, the shoes allow for sockless wear without causing irritation or discomfort.
