COMFORT ZONES
Each winter boot style is associated with a comfort zone. The comfort zones identified have been scientifically determined by an independent laboratory (the Textile Technology Centre) according to the number of calorific units (B.T.U.) meeting a specific need.
Factors such as the wearer's physical condition, duration, type of activity, humidity level and fit can influence the comfort felt. Comfort zone tests go down to -80F/-62°C. Results below this temperature are estimates based on the boot's insulating properties.
