Maplins had some battery powered heated insoles, which each ran on 3 AAA and lasted about 3 hours. I turn them on after about an hour just as my feet start to chill, then I can get a bout 4 hours before they start to chill again. It effectively means five hour rides are possible. There were 15 quid. Don't know if they have them this year, worth a look.
