This has been my norm for most of adult life, and I recently discovered Chaclas which kinda feel like a cross between Birkenstocks and Teva and are a breeze to walk 15 to 20 miles in. Highly recommend checking out their sandals
Can you link to the sandals you’re talking about? Only thing that comes up for me are the misspelling of chanclas, the generic word for sandals in spanish.
My family is a bit of a Chaco cult. We've climbed 14'ers in Colorado in them, my sister wore Chacos under her wedding dress, and I unintentionally ended up living and working close to the HQ.
I personally have walked 10 miles in a pair, but it was pretty casual walking.
Get them on sale, and send them in to get refurbished from time-to-time. They are fantastic.
