Rubber boots or Rain boots are waterproof by nature of course, but here are a few things you may find helpful. These boots come in a whole size only. They come in oxford, mid calf and knee styles. Some have nylon (fiberglass) or steel shanks for support depending upon the brand. Rubber boots are prone to puncture if you step on sharp objects such as nails unless they are equipped with a metal plate in the sole. A way to repair a rubber boot is to use a product called "Freesole" or "Shoegoo". You can also make your rubber boots more comfortable by using a felt insole to cushion your ride and also make the boot warmer in the winter. Wearing a heavier sock is another way to make your boot fit better. Rubber boots should not fit tight as you will need air circulation around your foot. Check with our boot fitters for individual questions about a particular style or brand.
