BEST FOR: Covering lots of ground.
THE TEST: The Radical ST are tough to beat for their durability and user-friendly features. The forged-aluminum toe piece, with handy guides that align your boot with the pins, is now easier to step into. The binding is also wider and stiffer laterally to power today’s bigger skis, and it’s incredibly lightweight—a huge plus after the first couple-thousand feet of climbing.
THE VERDICT: Outside of a pure randonnée race binding, the Radical sets the efficiency standard. 2.3 lbs.
