Some advisers have told him he should walk faster out of concern that his gait feeds impressions that he’s too old. And yet the White House is sufficiently worried about him tripping

One thing for sure, his 3 step "jog" that he seemingly does all the time surely doesn't alleviate any concerns.

He has new, wide & flat soled shoes to give him more of a platform/stability. Sort of like a duck’s webbed foot compared to a bird’s .... jogging even 3 steps in those things might be hazardous.
