I practically live in my rubber toggi boots, they are lined and very warm. They are fab for wading through mucky, boggy fields without your welly getting sucked off in the mud, never get hay stuck down them and they wash up great too. However they arent the most comfortable thing to wear when riding, I find my ankles can get quite sore on a long hack( but they are soooo warm).
I think it just comes down to personal preference. Mine are great winter boots, but will be put away in the spring and it will be back to short boots and chaps for me. Good luck
