Collonil Thermo de Luxe

The Thermo de Luxe insole is designed as an extremely thin sole that fits elegantly into any shoe without adding bulk. Nevertheless, the pleasantly soft and durable upper made of high-quality microfiber ensures an optimal climate inside the shoe. The cushioning foam mid-layer absorbs shock loads and guarantees optimal wearing comfort. The underside made of a special aluminum foil with an anti-slip coating serves both as a barrier against penetrating cold and provides secure grip in the shoe.
