well what type of riding do you do?? street, track, canyon's etc..?? In my opinion you can't have enough protection, i recently shattered my tibia & fibula in a crash w/ alpine star smx's on, I just replaced them with Sidi Vertigo corsa's & just by putting the boot on i can tell they will be a more protective boot than the smx's & they are alot more comfortable, they are about $100 more than the smx's but maybe if i had the sidi's on i would have over $80k in dr bills being paid out. Its just a matter of what price you want to put on your limbs, whether your riding to just commute or to stunt or to track etc.. i don't think you can go wrong w/ a full boot.. just my two cents & experience w/ boots
