Our exclusive artisanal process
Discover the craftsmanship behind our sustainable soles, made for comfort and performance using 100% virgin milk from Hevea trees.
ARTISAN-CRAFTED HEVEA SOLES
LACTAE HEVEA® soles are masterfully crafted from 100% natural virgin hevea milk, sustainably harvested from Hevea trees in Southeast Asia. Our exclusive artisanal technology creates a unique alveolar microstructure with thousands of canals, delivering exceptional shock absorption, lightness, and flexibility. Scientifically proven to reduce up to 50% of walking shocks (CTC study no. 46507961), these soles, with a density of just 0.9 g/cm³, float on water while offering durability, natural breathability, and a velvety texture. Renowned worldwide for their unparalleled comfort, LACTAE HEVEA®

Our Artisanal Process
Harvesting
Sustainably tapped from Hevea trees in Southeast Asia, virgin hevea milk is collected without harming the trees, promoting growth.
100% Hevea Milk
Over 50 manual steps across 7 to 10 days, including pouring, coagulation, baking, and drying, transform the milk into soles in Virieu, France.
Crafting
Artisans shape each sole by hand, ensuring precision and quality through traditional know-how, honed since 1971.
Refining
A meticulous drying phase creates the alveolar structure, resulting in lightweight, shock-absorbing soles ready for premium footwear with an 80% energy return.
A Driving Innovation
