If I'm going to be doing stuff on the ground with my horses, I wear my "barn sneakers" (basically just old sneakers that I don't mind if they get dirty and stuff)
If it's cold/muddy/rainy/snowy out, I wear these Ariat International - Ariat® Arctic Tall
These keep my feet nice and toasty!
For my birthday, my parent's got me these boots.
I only wear them for nice weather. Ariat International - Ariat® Heritage Ii Field Boot Zip
When I was younger, I had a pair of Ariat paddock boots. They were fine in warm/cool weather, but as soon as it was cold, my toes would freeze.
