I am relocating to my home town in the new year and have been offered a couple of days work at my old yard (riding school and livery yard). I will be taking hacks out but also doing a fair bit of yard work and pugging in muddy fields....what the heck do I wear on my feet?? I only have my old Hunters and jod boots which clearly won't do at all. Any recmmendations? Budget of about �70.
