Actually, no. The horseshoes of speed only benefit an animal (and the Zephyr ones only a horse), and a centaur is not an animal. And I'd recommend keeping it that way. I've seen Centaurs with those horseshoes (of speed) have base speeds higher than most foes' charging speeds, thus allowing them with Ride-by Attack and Spiritual Charge to maintain a vicious game of keep away. (Yes, you can ready to attack, but a) a single readied attack vs. a spirited charge = lose, every time, and b) if you just stand there, the centaur can assume you're doing this very tactic, laugh and pepper you with ranged fire). With the advent of Strongarm Bracers, a great deal at 6k, any Centaur of mid levels can easily afford to carry a Huge composite longbow to a fight, for a base damage of 3d6 +str mod, allowing for painful attacks even just playing it safe with hit and run tactics with the bow, no ranged feats even required.
Sorry for the rant, but allowing centaurs to use those horse shoes, IME is a very bad decision.
