INTEGRATION MAP — MIDSOLERECOVERED
ILLUSTRATIVE — FINAL DESIGN IN DEVELOPMENT
Adaptive Propulsion midsole
Superelastic elements engineered into TPU, PEBA or CMEVA foam: big rebound, softer landings. Tunable from soft to firm — one platform for daily trainers and race-day shoes.
Always on. It flexes under load and snaps back the instant you lift off.
PROBLEMS WORTH SOLVING
The super shoe changed racing.
It also left a list.
Runners, reviewers and researchers keep raising the same issues with today’s flagships. Here’s where Nitiwear is aiming — and how far along each answer is.
WHAT’S A SUPER SHOE?
Today’s top racing shoe: a thick, springy foam midsole with a stiff carbon-fiber plate inside. Since 2017 these shoes have rewritten marathon records — and set the template for premium running shoes. They’re fast, but they come with trade-offs.
SUPER SHOE VS. OUR APPROACH
Six trade-offs in today’s super shoes, and what Nitiwear is designing for. Tap + to see each.
An enhancement, not a replacement. NiTi is designed to work with the foams and geometries great shoes already use — making a strong platform last longer and respond better.

ANATOMY OF A NITIWEAR SHOE
Engineered
from the inside out.
Most shoes are designed outside-in: shape first, technology tucked underneath. Ours starts at the core — and every layer is built to work with it.

WHAT YOU’LL FEEL
The first stride sells it.
Every stride after keeps it.
HOW NITI COMPARES · 2026 FLAGSHIP RACERS
Foam cushions. Carbon stiffens.
NiTi responds.
Every flagship racer pairs a high-rebound foam with a rigid carbon element. Nitiwear keeps the foam — and trades fixed stiffness for a structure that adapts to the runner.

Energy return
Top 2026 super-shoe midsoles measure up to about 80% in independent full-shoe lab testing. Early NiTi components measured 78–88% in Heeluxe component testing — and adding SMA lifted a PEBA sample from 85% to 88%.
Full-shoe proof
Today’s flagships are race-proven. Ours is in the lab and moving fast, with full-shoe and athlete trials next. What comes after carbon is still up for grabs.
Energy-return comparison: about 80% ceiling per RunRepeat full-shoe lab testing; NiTi figures are company-reported component results from Heeluxe ASTM F1976-based impact testing (2025). Test methods differ, so figures are indicative, not head-to-head.
