Prevent yourself from getting cold feet on a days shoot with the Verney Carron Heated Insoles.

These flat heating insoles can be cut to fit into any type of shoe from EU sizes 38-46 thanks to its nifty size guides. 3 x AA batteries (not included) are all it takes to keep your feet warm for up to 4 hours in the field and the soles can be switched on and off throughout the day, via the pocket switch to help regulate a comfortable temperature.
