In the locals here in SoCal, I have worn mountaineering & hiking boots, trailrunners and low cut hiking shoes. My position for the MMWT is put something on your feet in which you have confidence. For me, that is a pair mid-weight backpacking boots.

Everytime I descend the trail my feet are killing me at the bottom but this type of footwear seems to work best FOR ME on this type of trip.

One thing I always to on the way down is to stop at Trailside Meadow, take off my boots and put my feet in the frigid creek for about 10 minutes. It makes a big difference. Dunking your head is also advised. It is the pause that refreshes.
