Patented Roomier Toe Box Geometry

A geometrically designed toe box with the widest radius in the category gives all five toes room to spread naturally, creating a broader, more stable base with every step. Your toes are your body’s anchor points — they should be working for you, not crammed together.

Posterior Ankle Stabilizer

A structured stabilizer spans the rear of the heel and runs along the plantar aspect of the mid-foot, providing consistent support along the entire rear chain. This directly addresses the ankle and heel mechanics that govern balance.

Neutral Stability Chassis

The shoe’s mid-foot frame provides a neutral, level platform that supports an upright posture and balanced weight distribution — reducing the compensatory lean and tilt patterns that cause instability over time.

High-Traction Proprietary Outsole

The outsole geometry is designed to support consistent gait and stride, optimizing balance at the point of contact where it matters most. The outsole geometry is designed to support consistent gait and stride, optimizing balance at the point of contact where it matters most.

Modular Insole System

The footbed is fully removable and compatible with custom orthotics, prescribed bracing, and aftermarket insoles. SENTRX™ works with your existing clinical care — it doesn’t compete with it.

Sta-Put™ Silicone Lace Lock

Silicone-printed laces grip the eyelets and stay locked once tied. No loosening mid walk. A small detail that makes a real difference when a loose shoe is a tripping hazard.

Depth-Inlay Upper Design

The shoe is built with extra depth to accommodate orthopedic devices and custom insoles — the structural requirement behind the L3221 / L3216 Medicare coding classification.

Proven. Measured. Medicare-Recognized.

SENTRX™ is built on a patented footwear platform validated across more than 50 clinical studies. The Centers for Medicare & Medicaid Services reviewed the clinical data and issued L-Codes L3221 and L3216 — making SENTRX™ the only footwear in its category to earn Medicare reimbursement coding specifically for balance and fall-risk support.

What the Data Shows

•    9% average improvement in balance and stability — across clinical study populations, and up to 18% improvement when compared to Hoka footwear.

•    50+ clinical studies — conducted over three years validating the SQAIRZ platform’s impact on fall risk, gait mechanics, and stability.

•    CMS L-Codes awarded — L3221 (Men) and L3216 (Women), covering up to $196.50 per pair under qualifying Medicare plans.

•    Falls are the third leading cause of death — among adults over 55. Death rates from falls have increased 30% in the last decade (CDC).

How Assessment Works (for Physician Programs)

SQAIRZ partners with Kinetisense®, a CMS approved markerless motion capture system that assesses a patient’s fall risk in approximately 20 seconds. This provides physicians with objective gait data —velocity, cadence, sway, and biomechanical compensations — that supports both diagnosis and Medicare documentation requirements.
