The combination of a Full Action toe piece and SPX heel deliver the longest elastic travel on the market for unmatched shock absorption. The result is instant power transmission and precise control with superior shock absorption to reduce unwanted pre-release. It's compatible with traditional Alpine (ISO 5355) and GripWalk® boot soles.
LOOK's SPX heel design offers 27mm of elastic travel for best-in-class shock absorption, confident retention, and a significant reduction in unwanted prerelease. An oversize heel pivot increases coupling strength (boot-binding interface) for more efficient power transmission.
