Thermal Wind 2.4 Thermal Cycling Boot Thermal Wind 2.4 Thermal Cycling Boot

Why wear this garment

Because the feet are the point most exposed to wind and temperature loss during pedaling.

The Thermal Wind Botín uses a Tek Series® membrane with osmotic technology that regulates humidity and internal temperature through vapor pressure gradient diffusion: sweat vapor escapes to the outside, while cold air and water remain outside.

Its three-layer structure generates a stable microclimate around the foot, conserving heat without a feeling of confinement.

The smooth exterior optimizes aerodynamic flow, reducing air drag and contributing to the saving of watts in headwind conditions.

The rear zipper system with reflective trim makes it easy to install, and the lower perforations keep the cleats functional, while the non-slip synthetic leather base prevents unwanted movements on the pedal.

Technology

• Tek Series® three-layer fabric: composed of an elastic outer layer, a windproof and water-repellent inner membrane and an internal plush support that preserves heat.
• Osmotic moisture management: the Tek Series® membrane regulates internal perspiration without allowing cold air to enter.
• Aerodynamic design: tight profile and smooth surface that reduces wind resistance.
• Non-slip synthetic leather base: prevents slipping and improves stability.
• Back zipper with reflective trim: makes it easy to install and provides visibility.
• Anatomical construction (left and right): ergonomic fit and precise alignment.
• Lower perforations and heel opening: allow the free use of cleats and better adaptation to the shoe.
• Additional reflective inserts: reinforce safety in low light.
