Data sheet updated in October 2026
The Core Carved Ultra 3 Pads & Straps are Core's premium twintip bindings, adjustable with a single dial. Core built this third version around the Reel Fit System: a central dial that uniformly tightens the strap over the instep, without pressure points. The Ultra 3 pad cradles the foot in a natural position, and the Union Baseplate fits most boards, both inserts and rails.
KEY INFORMATION
CORE CARVED ULTRA 3 PADS & STRAPS - Twintip pads and straps
What we like
- Reel Fit System: One dial, precise tightening, adjustable in both directions without interrupting your session.
- Evenly distributed pressure: The self-centering lacing runs on two rails and tightens the strap equally over the instep, with a marker to find your setting again.
- Ultra 3 Pad: Defined toe edge, open heel, ergonomic footbed: the foot stays secure without being locked in.
- Union Baseplate: 6 to 6.5-inch inserts and rails, position adjustable over 3 cm.
- Board Saver: An EVA layer limits sand and pebbles under the pad and protects the board's surface.
- Interchangeable padding: It can be changed in a few steps to adapt to your foot or switch from a summer to a winter setup.

DETAILED DESCRIPTION
Who is it for?
This is for the twintip rider who wants to precisely adjust their binding to their foot and style. They also want to adjust it to daily conditions, without sacrificing comfort during long sessions.
The Reel Fit System
A turn of the dial adjusts the strap. The self-centering lacing runs through two rails, tightening uniformly. Once adjusted, the strap stays in place, and a visual marker helps you find your setting again. Core designed the mechanism, assembled with LIROS lines, for sand and saltwater.
The Ultra 3 pad
The toe edge holds your foot in place, the open heel allows movement, and the ergonomic footbed maintains a natural position. Its firmness cushions landings without losing contact with the board. The padding is interchangeable to adapt the pad to your shoe size or boots, and the Board Saver layer keeps sand out from underneath.
Compatibility and Adjustments
The Union Baseplate accepts inserts spaced 6 to 6.5 inches (15.25 to 16.51 cm) and boards with rails. It moves 3 cm to adjust your stance. The only exception announced by Core is the Imperator V.

FAQ - CORE CARVED ULTRA 3 PADS & STRAPS
Yes, they will if your board has inserts spaced 6 to 6.5 inches (15.25 to 16.51 cm) apart or a rail system. Core only excludes the Imperator V.
The Reel Fit System dial lets you tighten or loosen the straps, even during a session. A visual marker helps you quickly find your preferred setting. The plate also moves 3 cm, so you can fine-tune your stance.
Core recommends size S for bare feet up to shoe size 43 (or 41 with boots thicker than 3 mm). Size L fits bare feet from shoe size 41 (or 39 with boots). If you're in between, both sizes could work. Core suggests trying them on, so come visit us at the shop!
The tightening system now features the Reel Fit System dial. The Ultra 3 pad has been redesigned, and the Union Baseplate now accepts rails. Plus, a new Board Saver layer protects your board.
