Only a suggestion but untill i started racing a it was a requirement for me to have proper motocross boots, i used safety wellys with 3 pairs of safety socks on. They give great stone protection as they are steel toecapped and the 3 pairs of sock gave great ankle support, and i did unfortuntly have to test them a few times!!
And the best bit of all was that they are completely waterproof!! great for deep mud and river crossings.
I got my wellies from screwfix for £9.99
Not suggesting for a minuit you compromise your safety on a bike but they are great untill you save up enough for a pair of boots. Thats what i did.
