Have you ever put a prochoice boot on one leg, and then a wrap on the other, worked your horse in them, then once you were done, put a thermometer in each and seen what the degrees were? A prochoice gets to be 20 degrees hotter than a wrap. Your horses legs are everything. If your horses legs are screwed so is everything else. You need to thing logically about this. I never have my wraps on for over 15 minutes(even that is over the limit) Sometimes they have to be on longer though. As soon as I am done running I take them off immediately, to let the legs cool down. I use to use prochoice boots, but now all I use is wraps, and will never go back to a prochoice boot. The wrap is still shock absorbant, but is still over 20 degrees cooler than a boot.
That is my opinion, everybody has different opinions and differnet views on everything.
