Flash TH Winter Shoe. A versatile road shoe designed to deliver comfort, warmth and performance from freezing temperatures to milder settings. Constructed from an insulating Thinsulate membrane, a winter specific material suitable for temperatures from 0 to +15°C, these shoes supply all the warmth and comfort you would expect for cooler winter conditions.

The shoes provide great thermal insulation, breathability and a snug fit with Northwave's Biomap Aero overlap. These performance orientated winter shoes produce the same excellent power transfer that Northwave owners have come to expect from their shoes - with a sole stiffness rating of 8 from Northwave.
