If you haven’t try the not that expensive plated offering from different manufacturers, that might be a starting point.
I feel you when it come to how you like the shoes. I was on your same boat until recently. But then, thanks to a deep discount on Saucony endorphin pro, I’ve been spoiled forever. I have a pair of adios 4, that have probably less than 50 miles on them. The Boston that I bought at the same time have more miles, but still have a ton left on them. I just stopped wearing them thanks the the endorphin line…
I recently got the endorphin speed, and it’s a fantastic shoe for long run and easy runs and really anything.
