Description:RST Tractech Evo D3O Boots – Black
Product Overview
The Tractech is RST’s long-running sport boot, and the Tractech Evo D3O is the version RST re-worked for 2026. RST describe the changes as a new inner foot profile that is slimmer across the forefoot for easier gear changes, a new toe slider, updated motion panels, a re-shaped upper, and D3O impact foam added at the shin and ankle.
RST state that those changes raised the boot’s CE rating to 2222 with the IPS and IPA markings — the markings that cover impact protection at the shin and at the ankle.
RST also make this boot as the waterproof Tractech Evo D3O WP and as a shorter-height Tractech Evo Short. This listing is the standard-height, non-waterproof boot.
