kanga, i can understand the hoof going on you if your realy going hard, but the spring, we use them daily and realy hard too, but i cant understand you needing a new spring so soon, do you go realy extreme on them, if not you may have bought a lower strength than you need, if you are going to buy new bocks i sugest you get a size higher, i may be wrong but anyway the sport is new and growing fast its a shame you have experienced this, i do agree that tyre socks will help keep the hoof in tip top condition so please look into that, as for springs if you need any advice please pm me and il see if i can help, good luck mate.
