Elos Thermal

What Elos Thermal does

Elos Thermal manufactures and sells a modular heated insole system under the brand name ELOS Thermal. The core technology is a reusable, trim-to-fit, orthotic-grade insole shell with micro-engineered weight-bearing pillars, a contoured heel cup, an internal heat storage cavity, and an integrated pouch for air-activated disposable heat packs that use precision-engineered iron filings to provide 8+ hours of regulated warmth. Two SKUs are offered: an ELOS Heating Insoles Starter Pack ($29.99 — one pair of reusable insoles plus two pairs of heat packs) and an ELOS Heat Packs refill pack ($9.99, four pairs), creating a razor-and-blame dynamic where consumable refills drive recurring revenue on top of one-time hardware sales.

The company sells primarily through its direct-to-consumer e-commerce storefront at elosthermal.com, powered by SHOPLINE and localized across 35+ European country/currency configurations, alongside a 100+ specialty retail store network concentrated in U.S. ski and sporting-goods retailers (Michigan, Pennsylvania, New Jersey, New York, Ohio). Customer segments are horizontal and span outdoor winter athletes (primary), cold-weather outdoor workers, outdoor recreation enthusiasts (hunting, fishing, hiking), and everyday cold-weather consumers. Marketing is content-driven, built around an SEO-focused blog, the branded 'The Next Layer' podcast, organic social, athlete ambassadors across collegiate and professional programs (MLS Charlotte FC, DC Power USL, University of Denver Ski Team, Baltimore Armor, Mount St. Mary's Golf), and a flagship GTM partnership with the National Ski Council Federation providing access to 300,000+ skiers.

Founded by Mount St. Mary's University student entrepreneurs Thunlwyn Garcia and Anthony Milazzo through the Palmieri Center for Entrepreneurship and headquartered in Baltimore, Maryland, the company operated as a 1-10 person team with no disclosed revenue, no disclosed institutional funding, and no subscription model. On May 4, 2026, Elos Thermal was acquired by Nufabrx Holdings, a leader in textile-based therapeutic technology, executing a student-venture exit and placing Elos's patented temperature-regulating insole platform inside Nufabrx's broader healthcare, sports recovery, and footcare distribution channels.

Revenue model

1. Heated Insole Hardware Sales: Elos Thermal sells reusable heated insole shells (the orthotic-grade base) as a one-time hardware purchase. The insole shell is a durable, trim-to-fit product designed for multi-season use across multiple pairs of footwear.
2. Heat Pack Refill Sales: Recurring revenue is generated through the sale of disposable heat pack refills. Heat packs are single-use, air-activated toe warmers that clip into the insole shell. Customers purchase refills in packs (e.g., 4 pairs for $9.99), creating a recurring consumption-based revenue stream.
3. Starter Pack Bundle Sales: The company sells a bundled Starter Pack ($29.99) that includes one pair of reusable insoles plus 2 pairs of ELOS Heat Packs. This bundle serves as the primary customer acquisition product, combining one-time hardware with an initial set of consumable heat packs.

Core offering

Elos Thermal manufactures and sells a modular heated insole system consisting of reusable trim-to-fit orthotic-grade insoles and replaceable, air-activated iron-filings heat packs that deliver 8+ hours of regulated toe and forefoot warmth. The products are sold primarily through the company's own e-commerce storefront and a U.S. network of specialty ski and sporting goods retailers, targeting consumers who face sustained cold exposure in tight footwear such as ski boots, work boots, and hunting boots.

Product overview

Elos Thermal offers a modular heated insole system consisting of two products: the ELOS Heating Insoles V2 (a reusable orthotic-grade insole with a built-in heat pack pouch) and ELOS Heat Packs (disposable, single-use toe warmers). The reusable insole shell features weight-bearing pillars for pressure distribution, a supportive heel cup, and a heat storage cavity, while the replaceable heat packs use iron-filings that react with oxygen to provide 8+ hours of regulated warmth. Users purchase the Starter Pack (insoles + 2 pairs of heat packs) and then replenish with Heat Pack refills.
