It's definitely a personal choice whether or not to use boots.
Some people refuse to do anything without boots, other find them useless.
Personally, I like to use boots. Every thing I can do to prevent an injury to my horse's legs, I do. Because my horse is a youngster under no strenuous work, she has a simple pair of protective boots.
However, as our workload progresses in these next few years, I will be buying her some Professional's Choice SMB boots. They offer support, unlike other boots(galloping, brushing, etc) which only offer protection if the horse were to bump his legs.
On the other horses I ride(trails), I just throw on a pair of combination boots and bell boots, mainly because they aren't my horses and I don't want to bang up a horse that I don't own.
Like I said, it is a personal preference and there are many different opinions on the subject. Posted via Mobile Device
