The structure of Astelu shoes is highly flexible in the barefoot shoe style, and they have very little shock absorption. The idea of barefoot shoes is to allow the foot to work in a natural way. - Airy, breathable textile surface - Thin, highly flexible rubber sole - Wide fit - Elastic laces - Heel and front are the same thickness, so the foot is level - Delicate wash in the machine at 30ºC, remove insoles and laces before washing and do not use bleach or fabric softeners Unlike in most product photos, the shoes have a light protector at the toe area. This protector can be seen in the extra image taken at our warehouse. The product does not contain PVC or fluorocarbons.
