What the T-4 lacks in sleekness, it makes up for with a strong, traditional fit and a road-like feel based around a stiff and supportive sole. Ventilation holes in the upper provide good breathability, allowing for quicker drying and fewer blisters coming out of T1. Showcasing an ultra-rigid heel- cup, the T-4 Air sets itself apart with a design that holds its shape even after hundreds of miles.
