I have the Equilibrium stretch and flex on Jazz if I'm doing any fast work, just to support his tendons. He's never done anything to damage them but prevention is better than cure!
He's also wearing over reach boots on the advice of the farrier - his front shoes have got a wider heel on them and he's more likely to pull them off if he stands on them so he's got the boots on to protect his shoes.
Yes he had shoes off as need a break from shoes and an thinking of leaving them off but farrier said I should use horse boot he suggested old macs just wanted to no other peoples thoughts
