My previous pair of Keens (a very similar model to Presidio that's not made anymore) were worn almost daily for 6 years, and traveled the world. Way too long, I'm sure, but I got rid of them because they looked beat up. They still felt like they offered good support. When I got the presidios, they felt almost the same as my 6-year-old version, which says a lot for how long these shoes maintain their structure/support. I did go through a brief, if worrisome break-in period with the new ones. I had some slight rubbing where the leather crosses over on the top and side. Between lacing them a bit looser and wearing them alternate days, they did break in after several days of moderate wear. A happy thing when spending $80 on a pair of shoes. Looking forward to wearing these for many years. And yes, they run small. I typically wear a 7 or 7.5. Ordered an 8. Feels good. Not for people with narrow feet.
