Jodhpur boots are a casual and affordable alternative to classic riding boots. They should be suitable for winter riding, as long as the following two conditions are met.
The boots should feature a warm inner lining, made of natural or artificial sheepskin, fleece, etc.. This will help keep your feet warm, both in the saddle and while at the stable. A water-repellent or waterproof upper is also important for keeping your feet dry during the winter. As long as your Jodhpur riding boots feature both of the above, they will get you through the winter without any problems.
