I thought about that and will make my final decision tonight. I really don't have any other boots except my Uggs, which would be OK, except my pants would be dragging on the ground, definitely causing me to trip. Same thing for my Merrell Mocs. Most of my dress pants are meant to be worn with slightly higher heels. Not high heels, but maybe 1/2 inch to 1.5 inches. The sidewalk where we will be walking is in a heavily travelled area around Northeastern U., so it is usually all cleared.
I can always insist that Steve let me hang onto his arm, taking him down with me, if I fall! (I won't tell you about the "accident" he had with an exercise ball, necessitating a meeting with the chain ring of my bike that is on the trainer).
