Hey Toast

Good questions man. All though the stilts are mainly aluminum there are many other components which are not aluminum and do rust very easily. If you use these in water they wont break or anything but you will probably need to replace alot of hardware as they will rust. Basically all the nuts and bolts. If you have bearing kits on your stilts then these may also need to be replaced or cleaned out very well.

So all in all, water and sand is not a good idea. Keep your Fly Jumpers away from the beach, at least not on the sand or in the water.

Bocking on sand would suck so much man. You would have no traction and the surface would be too soft for the springs to even work.

I walked with mine in 14 inches of snow once this winter. It was hillarious, I fell right in the middle of a fluffy snow bank and me and my Fly Jumpers got all wet and covered in snow. My bocks ended up being okay but this still was not a good idea lol. It sure had to be tried though
