Some brands make nice paddock boots and half-chaps that look like tall boots if you want to save your nice boots for shows. Think Ariat and treadstep have some.
Whatever you get, get boot covers for them and use them religiously whenever you aren't on a horse
Professional choice sport boots
The best boots are the Italian ones , Tucci is a very good brand , also tattini which is a bit cheaper. I recommend both and also they look amazing
