About a year ago I got cheap Decathlon rubber boots for a possibly one off lesson, not knowing if I'd get back into it. Fast forward one year and my feet are getting pretty cold in the Decathlon boots, even in three pairs of socks. The cold comes through the sole in particular when I'm walking around the yard.
Any suggestions for warmer/thicker soled boots? I find shorter boots more comfortable to ride. I'd rather not spend a fortune.
