The Aigle Parcour boots were handmade from 4 layers of natural rubber to provide a high level of comfort, strength, and shielding. The bidensity self-cleaning rubber sole is a bit lighter than the three density sole on the Iso and Vario, but still provides great grip, which makes this boot ideal for those who plan to be a bit more active in their wellingtons. The Cambrelle furnishings are sanitized to reduce odor, as is the fully washable and rapidly drying insole. The Parcour is an excellent boat for performance and flexibility.
