Heeluxe

What Heeluxe does

Heeluxe is a biomechanical research and development firm that provides science-backed footwear testing services to footwear brands worldwide. Founded in 2009 by Dr. Geoffrey Alan Gray, DPT, and headquartered in Goleta, California, the company combines human-subject perception testing, machine-based instrumentation, and a proprietary database of more than 3,500 tested shoes to deliver fit, cushioning, durability, stability, flexibility, impact, and temperature analyses. Its core technical assets include the SmartLast pressure-sensor fit system (integrated with Aetrex 3D scanning), the Time Machine rapid-durability rig capable of simulating 150 miles of running in 4.5 days, and the Hulk Impact Tester for ASTM F1976-compliant foam testing. In 2024 the company launched FITGalaxie, a cloud-based shoe testing database that allows brand clients to customize and access benchmarking results on demand.

Heeluxe sells primarily on a project basis, with engagements priced from $2,500 to $12,500+ and results delivered within two weeks; the website also lists $50/$60/$120 monthly subscription tiers tied to FITGalaxie-style access. The go-to-market is enterprise B2B, relying on direct website quote requests, founder-led industry presence, podcast and earned media (Forbes, Runner's World, Golf Digest, KEYT TV), and referrals. The customer base of 100+ brands includes Adidas, ASICS, Hoka, New Balance, Under Armour, Allbirds, Keen, Columbia, Tracksmith, SR-Max, and emerging names such as DAPS and Pashion Footwear, spanning running, lifestyle, outdoor, occupational, pickleball, and golf categories.

The firm is privately held, founder-led, and bootstrapped, operating as Heeluxe LLC with a team of approximately 11 specialized researchers and listed offices in Goleta, New York, London, Paris, and Hamburg. Strategic emphasis is on building the benchmarking database, expanding into adjacent footwear verticals (occupational, niche sports), and converting testing IP into a recurring SaaS product via FITGalaxie.

Core offering

Heeluxe provides outsourced, science-based footwear testing services to footwear brands, combining proprietary machine-based testers (SmartLast, Time Machine, Hulk Impact Tester) with human-based perception testing to quantify fit, cushioning, durability, stability, flexibility, and temperature performance. Engagements typically run $2,500-$12,500+ per project with results delivered within 2 weeks, and results are benchmarked against Heeluxe's proprietary FITGalaxie cloud database of 3,500+ previously tested shoes.

Product overview

Heeluxe is a footwear testing laboratory providing science-backed testing services for footwear brands. The company operates as a unified service platform offering multiple interconnected testing capabilities: SmartLast (pressure sensor-based shoe fit quantification), Time Machine (proprietary rapid durability testing), Impact Testing (ASTM F1976 compliant foam testing), Comfort Testing (human perception testing), and Stability/Flexibility/Temperature Testing. In 2024, they launched FITGalaxie, a cloud-based shoe testing database. Results are delivered within 2 weeks or less with video and print reports including recommendations for product improvements.

• FITGalaxie: The first cloud-based shoe testing database launched in 2024, allowing brands to customize results to their specific needs.
• SmartLast
• Time Machine
• Hulk Machine

Products and services

• SmartLast Fit Testing System Pressure-sensor based shoe fit quantification service that uses 3D foot scanning and pressure measurements across length, ball width, and toe areas to enable brands to compare fit against Heeluxe's large database of production shoes.
• Time Machine Durability Testing Proprietary rapid durability testing machine that replicates human movement to simulate 1 year of hiking/walking in 5 days or 150 miles of running in 4.5 days, providing durability predictions for outsoles and midsoles using human foot-mold casts.
• Cushion Testing Quantifies cushioning performance in a shoe during any activity (basketball, surgery, teaching, walking) to provide optimal cushioning recommendations for a target customer.
• Impact Testing (ASTM F1976) Machine-based foam performance testing using the Hulk Impact Tester per ASTM F1976, comparing cushioning, energy return, and compression of completed shoes, insoles, or foam plaques against thousands of competitor products.
• Stability Testing Stability testing using force plates combined with high-speed video to produce stability data that helps brands understand how shoes behave in real-world conditions.
• Flexibility Testing Measures how well shoes flex on a human (not a machine) to determine whether flexibility adjustments are needed in shoe designs.
• Temperature Testing Bilateral temperature testing protocol measuring foot temperature changes over 30 minutes of activity to determine which shoe model provides lower foot temperature and greater comfort correlation.
• Comfort Testing Human-based testing using wireless pressure sensors and perception feedback to analyze cushioning, fit, and overall comfort of insoles within actual shoe constructions.
• FITGalaxie Shoe Testing Database Cloud-based shoe testing database platform that enables footwear brands to access, query, and customize benchmarking results from Heeluxe's database of 3,500+ tested shoes, delivered via subscription tiers.

Quantifiable outcome

• Ball of foot cushioning breaks down first in running shoes at average 385 miles (vs. 707 miles for outsoles)
