I have a pair of Danner "Arcaidia" for almost 30 yrs. they have been resoled and now are my scooter boots.Unfortunately they now have some of thier lines made out of country.From my reading the big dogs use Lowa without issue.For work I use Thourgoods flat sole w/composite toe.They also resole well,here it's $ 60.00 for resole.But concrete eats them up sole,no heel makes them less of a tripper on the job.On snow or mud they are slippery.I go wide size for orthodics.
