Assos road cycling booties – GT Ultraz Winter Booties

The main membrane used is a double-layer ThermoShell, whilst the triple-layer SoftShell fabric provides ultra-effective protection against the cold, wind and damp. What sets it apart from neoprene, for example, is the fabric’s flexibility, but also – and above all – its breathability. When your feet aren’t damp, the cold can’t get in. The outer layer of the shoe cover has been treated with a water-repellent finish to make the fabric water-resistant. This Ultraz shoe cover rises slightly to cover your ankle. It fastens with a zip and also features openings for the cleat and heel.

The Ultraz range from Assos is the most technical and protective option for winter. If your feet are particularly sensitive to the cold, we also recommend the Ultraz range of socks.
