Additionally, the Classic GTX sports a direct-injected PU midsole, Stinger III spikes with a Q-Lok receptacle and a performance-enhanced insole unit.
The Classic GTX's all-leather upper provides it with high-quality comfort while its Gore-Tex lining makes it completely waterproof while quickly wicking away internal moisture. Its dual-density TPU inserts provide the Classic GTX with consistent support and comfort as they are both flexible and lightweight. Meanwhile, the Classic GTX's Q-Lok spike receptacle utilizes a quick locking system for quick and easy removal or replacement of its Stinger III spikes.
