The MT91s are full hiking boots but with cleats, I can walk around all day in them I only take one pair of shoes, to deal with wet feet I carry a pair of English made Sealskinz socks that I wear around with wet shoes after riding. The socks get thrown in with the washing. Feet stay dry and warm and doesn't matter that the shoes are wet. I also wear them with a pair of thongs (flip flops to the rest of the world) around camp if the grass is wet.
Mind you I grew up with toe clips and straps and needing to keep a cast iron shoe last to re-nail the blocks onto the soles of my leather shoes. Now that is a zero float system. Makes me laugh when people talk about struggling to unclip from SPD pedals. You need to try and get out of a proper toe clip system in a hurry to see what real foot retention is. Anticipation was everything and if that failed learning how to topple gracefully was important, because there was no such thing as getting out at the last second. Mind you there's no graceful way to flop around on the ground like a beached fish trying to undo the straps and twist your feet out.
