Z1 Classic Sandal (Men)

I recently purchased a new pair of Z/1s, and they are 1/4" too short compared with my older Z/1s. I've been a customer, furthermore a raving fan, for 21+ years, but now the product now longer fits. I purchased the next size up (size 12) to see if they would work, but they are too long for my foot plus the heel leash is too loose. I called for support, but half sizes are not possible and heel leash adjustments are only possible through the custom shop (higher cost vs. stock items plus additional lead times). As an engineer, I'm utterly baffled why such a change would be made that alienates existing customers. It's always easier and less costly to keep an existing customer than to find a new one. So sad to post this since I even have the "Chaco Professional" sticker to prove my brand love that started so long ago.
