Four year service life

I've had my motorcycle gear for a little over four years now. The pads in the helmet are pretty worn out along with the chin strap. The boots have most of the rubber worn off the sole. The gloves have lost a lot of the decorative stuff on them. So I bought a new helmet, but still using the boots and gloves are they still provide the proper protection. I think I can get the boots resoled and as for the gloves, well, they still work. I don't want to buy new gear because the boots are well over $300 and the gloves are close to $200.
