Your What did what?..You have pneumatic insoles in shoes?.... My Walking boots have thick one inch deep soles with grip-a-wet-toad treads... I am well versed in hill walking, I know simple works best, and footwear should be HARD, SOLID, and other words that mean will come back maybe scratched but otherwise good to go for at least a thousand miles more than you expected. Mountain Rescue... I have rescued people in Pumps, Flip-Flops, Trainers, and actual high heels from mountain trails.. all with foot injuries. Is this a bi-cyclist reference?... if not, please explain?... the material of the insole suffered catastrophic structural failure. we bought two special wheels for the medical response rigs that are most likely to be doing long trail pack-outs. looks somethign like this: the proper use of it is to have two people in front pulling it, and two people in back pushing it. done properly, it works like pushing a slightly wobbly cart. however, if the people in back insist on pushing upwards on it, the people in front get driven into the ground. the particular leverage it gets is as much the opposite of ergonomic action as I have ever found.

So many leverage points, it kinda looks uncomfortable, and extremely anti-stable.........

So many leverage points, it kinda looks uncomfortable, and extremely anti-stable......... it is pretty wobbly - but it is the most maneuverable. keep in mind you are carrying an injured person in a litter, here. done properly, four people can carry a "big boy" over a considerable distance without straining themselves. on level ground - two people could carry YOU, easily.

I am still working out the turning circle, on a tight bend, do you swing the people, or lift the wheel off the ground, how high does that wheel make the litter, how manoeuvrable in tight circumstances, can you take the bloody wheel off when needed.....

The other end can hang over open air if necessary to make the turn.

It looks like someone tried to re-invebnt the wheelbarrow, and missed. But then again, if I used it, I would probably see why its so good... This is all remembering I used to do Mountain Rescue, and we didnt have anything like that.
We did trial a two-wheel "Trailer" type thing, but the wheels got in the way on rocky terrain.

This is all remembering I used to do Mountain Rescue, and we didnt have anything like that. We did trial a two-wheel "Trailer" type thing, but the wheels got in the way on rocky terrain. that is why just one big wheel in the middle. yes, there are terrains it won't work over - and those are the terrains we don't stop calling for more manpower until we have at least 10 able bodies. the critical thought is: how many people would you send to carry a 200# man a mile in a litter, nonstop? we send 6 - which gives us two to trade out.
