| Size | US Men’s | UK | Euro | Mondo |
|---|---|---|---|---|
| Small | 6 – 8 | 5 – 7 | 38 – 41 | 24 – 26 |
| Medium | 8.5 – 10.5 | 7.5 – 9.5 | 41.5 – 43.5 | 26.5 – 28.5 |
| Large | 11 – 13 | 10 – 12 | 44 – 46 | 29 – 31 |
If you ride at the edge of two sizes, size down for a responsive, locked-in feel or up for a more relaxed fit. Boots should sit snug inside the binding with no heel lift.
Component Breakdown
S3 EXP Duraflex ST Baseplate
When your splitboard bindings ride like your regular bindings, it's easy to enjoy the ride down. The S3 EXP Duraflex ST baseplate is the key ingredient — designed for splitboard touring with the responsive feel of a regular binding.
EXP4 Duraflex ST Highback
Designed for longer tours and bigger backcountry lines. The EXP4 Duraflex ST highback features 15% more fiberglass than the previous generation EXP3 — stiffer for charging and more responsive on the descent.
ExoFrame 4.0 Slim Ankle Strap
25% lighter than the standard ExoFrame 4.0 ankle strap — and still just as comfortable. The Slim version is dialed for splitboard touring where every gram matters on the up.
TS 4.0 Phantom Toe Strap
Keeps you locked in for the ride down without letting you know they're there. A shorter buckle base helps reduce weight and stack height — perfect for the touring mindset.
Magnesium S1 Ratchets
Magnesium S1 ratchets are Union's answer to the elements. A fully integrated spring protected from the harsh outside provides fast, fail-free ladder action on every transition.
Extruded 3D Aluminum Heelcup
Designed for optimum heel hold and minimization of drag — critical for splitboard bindings where every ounce counts on the skin track. Backed by Union's lifetime warranty.
Non-Stick HP EVA Footbed
Next evolution of Union's non-stick EVA technology. Non-Stick Hot Press EVA creates a closed-cell finish that's 100% waterproof — moisture won't soak in on hot spring tours or wet boot-packs.
HP EVA Bushing
Union's HP EVA bushing provides additional dampening between baseplate and pucks — reduces chatter on firm skin tracks and softens landings on big-mountain descents.
Charger Touring Bracket
No pins needed. Union's Touring Bracket is the future of splitboard binding technology. Simple, easy to use, and incredibly lightweight — the cleanest touring interface on the market.
Dual-Lock System
Union's innovative Dual-Lock system makes switching from tour mode to ride mode fast and frustration-free — no matter the conditions. The cleanest splitboard transition on the market.
