Birkenstock paris and londons from the 90s resoled three times. Still in use. Beautiful patina

Several pairs of boston resoled many times. They repair chips and holes in the cork at the time.

Let's see, 80 bucks for a resole or 170 bucks for a new pair.

They can do heel wedges as well.

My philosophy is maintain and have stewardship rather than consumption and disposal.

The sandals you can get a full new footbed. Still cheaper than a new pair

Edited to add: I threw away a pair of londons after hiking Hadrian wall. Too far gone and gross
