SOLARCORE® Insulates Merrell’s ISPO
Award-Winning MTL Thermo Rogue 4 Boot O
sets a new , a NASA-inspired proprietary
insulation technology, has helped Merrell earn a 2022 ISPO Award for the outdoor hike and footwear brand’s MTL Thermo Rogue 4 Boot. Recognized for its ability to maintain superior conductive thermal properties under compression, SOLARCORE composite foam is powering the next generation of lightweight, cold-weather, performance footwear. Traditional foam insulation used in footwear applications rely on the principles of loft–bul k and airspace–to provide warmth to the wearer. Under the weighted compression of footsteps, thermal warmth becomes compromised as the loft in these insulations begin to break down.
Developed using NASA-inspired insulation
materials, the same technology used to insulate spacecraft in the -450F environment of space, SOLARCORE represents a leap forward in foam composites. At only 2mm thick, SOLARCORE offers a thermal rating of 30 mW/m-K–nearly half the thermal conductivity of other leading foam insulators– providing exceptional warmth to volume performance. Additionally, under extended periods of compression, SOLARCORE’s thermal properties do not break down—a level of performance current foam alternatives cannot match.
These attributes are what attracted Merrell to SOLARCORE when the footwear brand set out to develop a lightweight running option for winter athletes, the MTL Thermo Rogue 4 Boot. Just two millimeters of SOLARCORE incorporated into the Rogue’s toe box and insole provides runners and hikers with lasting warmth in a lightweight package. This performance was noted by ISPO’s discerning jury when the panel awarded the MTL Thermo Rogue 4 Boot with best, Light Boots for Winter Hiking. “This is the kind of shoe modern hikers and outdoor enthusiasts are looking for in winter—athletic and durable winter hiking boots,” the Award Jury wrote.
“We’re thrilled that Merrell was able to make the most out of SOLARCORE and recognize its capacity to revolutionize product insulation.”
“We’re thrilled that Merrell was able to make the most out of SOLARCORE and recognize its capacity to revolutionize product insulation,” commented Michael Markesbery, the principle behind SOLARCORE technology. “Clearly, the jury at ISPO agreed and rewarded Merrell for designing a great boot and taking the leap toward innovation.” For all SOLARCORE media inquiries, please reach out to Sam Morse: sam@
