Modified 29er hardtail here (was a Specialized Hard Rock before I replaced everything but the frame). I do the exact same thing. Clip-ins just never quite worked for me. I understand the efficiency gains and weight savings (don't really care about weight that much, it's a MTB), but being able to just hop on and off my bike without special shoes is nice. I also use 5.10 skate shoes for longer or more aggressive rides.I went MTBiking on Christmas Eve up here, on trails that are usually too wet to ride this time of year unless they are frozen (they were). My bike started out as a Specialized Stumpjumper but is now a franken-bike as front fork, main shock, front rim, tires, brakes, have all been replaced and a dropper post added.
I've gone full old guy with shin shredding platform pedals, and find using them with the 5.10 shoes pretty awesome with no clopping around when walking. I put platforms on my gravel bike too, and often ride in Tevas.
