| LIGHTCELL™ | This compound is produced using the industry-leading supercritical nitrogen foaming process. It is environmentally friendly and offers a 50 per cent reduction in weight and a 45 per cent increase in energy return compared with traditional EVA mid soles. |
| ZEROSAG™ | To create the smoothest possible stride, Mount to Coast drew inspiration from the automotive industry to develop ZeroSag™, the revolutionary midsole insert co-developed with BASF. Durable, comfortable and offering impeccable energy return whatever the temperature, it guarantees ZeroSag™ extraordinary cushioning on even the longest runs. |
| GOFLOW™ | GOFLOW™ is a midsole design, the result of extensive, industry-leading research, designed to provide extra support and allow you to enjoy a natural, fluid stride from heel to toe. |
| TUNEDFIT™ | The double lacing system offers TUNEDFIT™ a customisable fit for the forefoot and midfoot separately. Because we know that, as ultrarunners cover long distances, their feet can swell and change shape, and that having a shoe capable of adapting to these changes whilst running can make the difference between mild discomfort and injury. |
