Got a new pair on the way. Posture supportgreat fit, they definitely start to squeak, but my lower back feel much better after regular use. Better than most tactical work boots. Dont wear in a combat situation, especially on reconnaissance. The squeak is definitely loud enough to pinpoint a target, but it is not really noticeable in a noisy civilian work environment. The arch in the heel that supports lower back posture is the winner in this boot. NOTE: Best when used with doctor prescribed inserts. Remove the inserts that come inside these boots first.
