Prolite event boots (front and back) - they stay put, they don't slip/twist/rub, the velcro stays done up, they don't absorb water and dry quickly. Even after 8 years they still looks smart and scrub up well.
At home for hacking and schooling, Woof Club boots in front - can be a bit of an idiot at times and has kicked himself in the past when a*$I@g around, last time he did it he ended up throwing a splint so it is just safer to have some protection on his legs.
Dressage Warm up - He did have white boots but my washing machine ate them at he end of the eventing season so he now has a very smart set of white bandages.
When ever jumping or doing pole work he wears Trizone Tendon and fetlock boots - no point risking a knocked tendon!
XC - Woof Ultra Boots and Trizone no turn Overreach Boots in front, NEW air Cooled xc boots behind. These are just about the only decent XC boots that we could find to fit him!
At home, trizone brushing boots. They're nice and comfy, don't rub, the velcro is good and they stay put and they wash well. Plus they're brown which is nice on chestnuts. Plus they didn't cost too much.
Out I have a pair of leather jeffries tendon boots and a pair of NEW fluffy white brushing boots depending on what I'm up to.
I'm too pansy to need anything for XC/hunting as I won't do it!
