I put polos on because it makes me feel better and I love the patterns. You can find just about anything on ebay
. I don't use them most of the time.
My mare tore a ligament on the backside, just below her knee a few year ago. I am a little paranoid about it. I usually put icy hot on it then wrap it, if the ring dosent have excellent footing, it really depends on how I feel at that moment though. I don't have any boots for her. (Well I have a pair of open fronts, but I never actually used them.) We only do flat work and light trail riding. She gets ridden like maybe 20times a year. I would never use polos on the trail, a branch could pull them or unravel them. They are great for desensatizing.
I didnt think they would work well as standing wraps. They have to much give/stretch for me. I prefer plain old standing wraps and no bows.
