Marsblade’s i2 Kit V-Edge changes the skate’s pitch through a rocker mechanism while keeping a conventional steel runner. The construction separates the holder’s movement from the runner’s profile: the kit includes five pairs of rocker-radius inserts to adjust the motion, and stainless steel runners supplied with an 11-foot radius.
Marsblade says the runners can be profiled and sharpened like regular skate blades. The holder also uses a quick-release runner system. For mounting, the company says the i2 shares the hole pattern of Bauer TUUK holders and recommends installation by a pro shop or equipment manager. Its listed holder sizes run from 238 to 306.
There is research behind the dynamic-holder idea, but the date and measured outcome matter. In a release dated 1 October 2025, the Swedish School of Sport and Health Sciences, GIH, reported a study conducted in collaboration with Marsblade. Elite players tested dynamic and fixed holders over sprint distances from 5 to 40 metres. GIH said the dynamic holder improved backward-skating speed and finishing time by between 1% and 2%.
That report supports a specific result under the study’s conditions. It does not establish that every player will see the same gain across every skating movement. GIH described further biomechanical research as ongoing.
On 1 October 2026, Marsblade’s US price data listed the i2 Kit V-Edge at US$129. The 263 holder size showed stock in the US market’s product data. The kit contains two holders, two stainless steel runners, the five insert pairs, a quick-release key and a user guide. That price covers the kit; fitting it to an existing boot is a separate job.
This is a look at the holder’s construction and published research, rather than a report of a new October 2026 launch.
