Think about what sort of riding you'll be doing, and when you¹ll be doing it.
If you'll be commuting throughout the year, there will be days when you rue the purchase of those vented summer race boots!
The theory behind finding all-weather boots that fit are the same as with summer boots.
Try on as many pairs as you can, with your normal riding trousers.
But when you're looking for all-season boots, although protection will still be a key consideration, you should also be looking at weatherproofing.
Look for names like Gore-Tex, which will indicate waterproof qualities. Be especially careful to ensure rain is not likely to get past zips, Velcro flaps or down the top of the boot.
A non-slip sole is something worth keeping an eye out for, as petrol station forecourts get pretty slimy in the winter months, especially when there¹s spilt fuel on the ground.
