INJECTED MAGNESIUM RATCHETS
This Union exclusive process produces a material four times the strength of aluminum with only half the weight. Plus, magnesium is easily recycled and remains the eighth most abundant element on the planet.
FIRST CLASS COMFORT
Over-padded ankle straps, Multi-Density Thermoformed EVA Bushings and UltraGrip toe straps equip the Trilogy with all day comfort, all season long.
DURAFLEX ST TRILOGY BASE
Blended to provide a smooth and responsive ride, Duraflex ST Nylon retains this intended performance in a broad range of temperatures.
MULTI-DENSITY THERMOFORMED EVA BUSHINGS
Multi-Density Thermoformed Bushings sustain their function season after season - unlike competitors who use urethane, rubber or other materials that change color and become brittle over time.
EXTRUDED 3D ALUMINUM HEELCUPS
The rigidity and strength of Extruded Aluminum acts like a roll cage on a race car - stiffening the entire chassis. The male/female connection with the base provides seamless response.
A female specific version of our iconic Force Highback, the Trilogy versions are tapered towards the top, providing flex and tweakability where you want it, support and durability where you need it.
3D SYMMETRIC ANKLE STRAPS
Direct Connect System locks you in with zero strap elasticity. The Multilayer Core inside provides supreme comfort, and conforms across the top of your foot.
This Union exclusive process produces a material 4 times the strength of aluminum with only 1/2 the weight. Plus magnesium is easily recycled and remains the eighth most abundant element on the planet.
