My thin-soled Paso goes well in Renegade Vipers for riding - they are my "go to" riding boot.  I have Scoot boots for him too - but they offer less protection than the Vipers and I don't think he would be handle most of my area trails very well in them.
He also has a pair of Old Macs (think the Gen 2 ones) a friend gave to me because she didn't need them anymore.  They are 'clunky' on him - really mess his gait up for riding.
I've used all three when Salsa has been a bit ouchy on his dry lot even though they are not therapeutic boots (and luckily all three gave him instant relief).
