Has anyone used these before, and If so, what are the general thoughts. How do they compare to other magnetic and therapuetic boots like Equilibrium or Premier Equine range?

We are currently using PE magnetic over reach boots, but they now need replacing & I'm considering these - but they do have a larger price tag than the PE boots, so am keen to see what other people think of them.

Finally, what is the sizing like? My native only has short pony legs & if these are designed for long legged types, they'd probably be far too big for him!
