Unless he's overreaching, or your shoes are especially long behind (as egg bar shoes sometimes are) you shouldn't need them. If you turn him out in pasture a lot though, you may want to get a pair of cheap pull on bell boots, as many horses overreach when galloping around in pasture, and a $10 (http://www.doversaddlery.com/easy-stretch-bell-boots/p/X1-0410/cn/120/) pair for preventative measures may be worth the cost.
