Two Army dudes with quite a few miles on foot.
Elder son is a Garmont fan boy. Doesn't like lightweight "slipper boots" Heaviest concentrated footwork was in Ranger School.
Younger son doesn't have his tab yet like the elder but has logged more real world rucking and patrolling time than his big bro. He loves him the sort of lightweight Nike boots.
I think I'll lean to the latter myself.
