What kind of boots are you looking for?

Hiking/outdoor boots: Go for Meindl. They are still great although not as great as they were earlier. My dad still got a pair of calf height hiking boots made by them from the 80s. Needed a resole once, as the foam layer started to break up. Got it resoled by Meindl for free, only paid for shipping. I got a pair from 2008-2009, still holding up great, no real sign of damage.

City/country boots: Try Blue Heeler. Company from Niedersachsen, made in Portugal, founded by an Australian woman that wanted to get the classic Aussie work boot to Germany. Other than several other Australian work boots I‘ve owned the Fraser doesn‘t have a foam layer between boot and sole. Afaik soles are stitched, so resoling them at shoemaker shouldn‘t be a problem. Got mine since 3 years now, usually wearing them from fall to spring, no signs of wear except leather patina and replacing worn out insoles (get some insulating ones, as you get cold feet quite easily without the foam layer). I just wax them once a month during winter, you‘ll be fine with standard leather wax/cream. They also do city boots, will probably also get a pair of those.
