Just make sure your horse is used to the supports before you go. My husband's gelding would have no part of the things so we gave it up as a bad idea and resold them on ebay
. We normally leave the legs bare and the only reason we got them for the gelding was a vet we normally don't use said it was a good idea. Turned out it wasn't...especially in HIS (the horse) opinion.
I think there are valid pros and cons on the use of sport wraps. If the horse needs the support or needs protection then they are good. Some riders like them as a cover against scrapes and cuts, and others don't want to risk getting sticks and junk up under the wrap if they do a lot of off the trail riding.
Pretty much simply a personal choice.
