Step On
Burton
The Burton Step On system has redefined fast-entry bindings by replacing traditional ratcheting straps with a direct boot-to-binding mechanical connection. Targeted at resort riders who want to eliminate the hassle of strapping in after every chairlift ride, the Step On uses three connection points—two toe cleats and one rear heel cleat—to lock the boot into place. Independent reviews frequently highlight the system's exceptional edge-to-edge responsiveness. Because there are no straps to stretch or compress under load, toe-side and heel-side energy transfers instantly to the board. The elimination of ankle straps also means zero top-of-foot pressure points or strap slippage. Once you get off the lift, stepping in requires a simple heel-toe click, and a side-mounted lever allows you to exit in one quick motion. The primary drawback is the closed ecosystem: the Step On bindings work exclusively with Burton Step On compatible boots. You cannot use your favorite conventional footwear. Additionally, riding in wet, sticky snow can lead to ice accumulation around the heel pocket, which requires riders to scrape out the mechanism before they can lock in cleanly. **Highlights** - Three-point connection interface eliminates all straps and ratchets - Instantaneous edge-to-edge power transfer with zero strap flex - Quick-release lever enables effortless one-handed exiting - Re:Flex baseplate preserves natural board flex underfoot - Eliminates top-of-boot pinching and pressure points entirely **Watch-outs** - Proprietary system requires purchasing dedicated Step On boots - Snow and ice can pack into the heel cleat and prevent engagement - Lacks the fine-tuned fit micro-adjustments of traditional straps

Trilogy
Union
The Union Trilogy is the benchmark women's all-mountain binding, mirroring the bombproof durability and performance profile of the men's Union Force. Aimed at intermediate to advanced female riders who charge steep terrain, carve aggressively, and demand a binding that will not wash out at high speeds, the Trilogy delivers uncompromising support. Constructed with Union's women-specific highback geometry and proprietary Duraflex nylon, the Trilogy provides a rigid, dependable flex that remains consistent regardless of temperature drops. The Exoframe ankle strap distributes pressure broadly across the front of the ankle, locking the heel securely into the pocket without creating painful pinch points. Review outlets frequently point out the Trilogy's longevity, noting that its extruded aluminum heelcup and magnesium hardware routinely outlast multiple seasons of heavy abuse. Because the Trilogy leans toward the stiffer side of the all-mountain spectrum, it is not the best match for casual beginners or park riders who prefer a loose, forgiving feel for buttering and rail tricks. At roughly four pounds, it is also slightly heavier than some female-specific competitors that prioritize lightweight nylon over all-out durability. **Highlights** - Women-specific highback geometry tailored for female calf profiles - Duraflex ST nylon construction maintains uniform flex across extreme temperatures - Exoframe 4.0 ankle straps deliver uniform hold without hot spots - Extruded 3D aluminum heelcup provides superior strength and heel hold - Universal disc compatibility fits 2x4, 4x4, and Channel systems **Watch-outs** - Stiffer flex profile can punish sloppy footwork or novice technique - Slightly heavier than lightweight, park-focused women's bindings - Forward lean adjustment requires a tool on select configurations
