DESIGNED BY MEDICAL PROFESSIONALS —The Comfort Cool Ulnar Booster was specifically engineered for people experiencing pain on the pinkie side of the wrist — including TFCC tears, ECU tendonitis, midcarpal instability, and persistent wrist pain after a fracture. This is not a general wrist brace — it is a targeted solution for a specific problem. FOAM INSERT FOR TARGETTED RELIEF — A foam boosting cushion placed over the pisiform helps create a counterforce effect to realign and stabilize the carpal bones while depressing the ulnar head. When worn correctly, you should feel the counterforce on the ulnar (pinkie) side of your wrist. TWO ADJUSTABLE COUNTERFORCE STRAPS — Unlike standard single-strap wrist braces, the Ulnar Booster features two fully adjustable straps that wrap in opposite directions around the wrist. This biomechanically correct design helps realign and stabilize the carpal bones and support midcarpal instabilities often caused by ligament damage. SOFT, BREATHABLE & SKIN-FRIENDLY — Made from thin 1/16" (2mm) perforated neoprene with a soft terry cloth liner for breathability, wicking, and comfort against sensitive skin. Trimmable for a more personalized fit. Hand washable, air dry. SELECT YOUR HAND & SIZE FOR A PERFECT FIT — Available in multiple sizes for both right and left hand orientations. Use our size chart to measure wrist circumference and select the correct combination for a secure, supportive fit where you need it most.

The Wrist Brace Built for the Pinkie Side

If you've been told you have a TFCC tear, ECU tendonitis, midcarpal instability, or persistent wrist pain on the ulnar (pinkie) side — you already know that a standard wrist brace isn't going to cut it. General wrist support doesn't address the specific biomechanical problem that causes ulnar-sided pain. The Comfort Cool Ulnar Booster does.

A Mechanism Designed by a Hand Therapist

The Ulnar Booster was specifically engineered for people with ulnar-sided wrist pain and midcarpal instability. It works through a counterforce system: a foam boosting cushion placed on the pisiform — exactly where the ulnar carpus needs support — combined with two adjustable straps that wrap in opposite directions around the wrist.

Together, these elements depress the ulnar head while boosting the ulnar carpus, helping to realign and stabilize the carpal bones. When worn correctly, you should feel the counterforce on the ulnar side of your wrist. That sensation is the brace working as intended.

Not a General Wrist Brace

This product is designed for a specific condition profile: TFCC pathology, ECU tendonitis or subluxation, midcarpal instability, and persistent ulnar-sided pain after a wrist fracture.

Built for Comfort and Long-Term Wear

Made from thin 1/16" (2mm) perforated neoprene with a soft terry cloth liner, the Ulnar Booster stays cool, breathable, and comfortable against sensitive skin during extended wear. Trim the strap lengths, thumb hole, finger openings, and splint edges to customize the fit. Hand wash in cool water, air dry.

4 Sizes — Right and Left Hand
