Cold feet and overshoes are two of the worst aspects of a British winter. Taking its cue from the world of skiing, Sidi is hoping to have banished both by way of the introduction of its heated insoles.

With battery technology moving forwards at lightning speed thanks mainly to mobile phones, it is now possible to fit a small battery into a shoe insole. That, combined with a series of elements that are controlled by a temperature sensor, makes for an ingenious foot heater.

A small key-fob style remote control enables easy operation. The soles keep the shoes at around the 38-degree mark so these should herald the end to cold feet. The only down-side is the £175 price tag.
