The Parcours Iso are anti-fatigue rubber boots that insulate from the cold down to -20 degrees Celsius with their 4.5 mm thick neoprene lining. Neoprene is a reference in terms of insulation; it contains micro-bubbles of air to improve the insulation of the feet and legs. With their tri-density rubber soles, Parcours boots offer comfort allowing you to walk further without getting tired. The damping cushions in the heels act as return springs, resituating part of the energy used in taking a step. With their adjustable tabs and gussets, these boots fit snugly to your legs. Fully zipped, making them easy to put on and take off. This rubber boot is handmade in France by one of the Aigle's master rubber craftsmen.
