The Regatta Ladies Riverbed X-LT shoes are designed for lightweight trekking, trail walking & fast light sports. They use an Isotex membrane to provide waterproofing & high levels of breathability. Moisture is drawn away from the skin by a wicking lining which works synergistically with the Isotex to keep your feet dry in both hot sweaty & wet conditions. The suede upper is also Atl DWR treated which causes water to bead up, rolling off the surface before it has time to wet out the external fabric. The Riverbed shoes are built around a womens specific, athletic lasted, lightweight X-LT sole, which uses compression moulded EVA & carbon rubber to provide exceptional stability & impact protection underfoot.
