The LYTERACER 4 running shoe is designed for competitive runners seeking good stability and an energized feel underfoot. With FLYTEFOAM Propel cushioning underfoot, this shoe creates a more responsive rebound in each step. This midsole material transfers the energy absorbed from impact to your next step, propelling you forward faster. For increased stability, the shoe features TRUSSTIC technology, which reinforces the middle part of the sole. By improving support, you're able to experience a more confident stride.
