The Speedland RX:LDVL trail running shoe is built to move between a daily trail run and an ultra race effort without swapping shoes. A removable carbon plate and a removable ATPU foam midsole let the fit and response change with the effort, while a BOA Fit System paired with PerformFit Wrap locks in a precision fit through technical terrain. What Our Gearhead(R) Experts Are Saying:"I ran an easy recovery day and a race-pace long run in the same pair, pulling the carbon plate for the slow miles and dropping it back in before the effort ramped up. The BOA dial held the fit exactly the same both times, so nothing about the shoe felt like a compromise at either end."
