Every 100g on a shoe increases oxygen consumption by roughly 1% during running. By dropping to 115g, the Cold Waters Trainer lowers your energy demand per stride, making threshold paces feel more sustainable over longer repeats.

While the game is intended to be a punishing simulation, a trainer provides a bridge for those who want to experience the thrill of the "Silent Service" without the frustration of repeated restarts. WeMod Community Cold Waters Cheats and Trainer for Steam - WeMod Community
