Which shoes do you use? I use ASICS GT-2000s and they usually last 350km to 400km, or a year, in my case (a couple 5k to 8k runs per week). I guess different styles of running could also cause different amounts of wear and tear.

Adidas Adios stuff has worked best for me. But I’m also 56kg so they prob last longer than they would for a bigger person.

As a "non-runner" who just needs running shoes for the gym and walking around, I found great luck at Thrift Stores. What I found us a marathoner will buy a pair of Nike's and run that 600-700km until they are "spent" and give them to Goodwill. While they aren't good for running anymore, I found most to have plenty of sole left for 6-7 months of walking and going to the gym, all for around $10.

This is probably not the best for my feet, but when I bust a hole where my big toe goes I feel less bad because I spent $10 and not $100.

Wow, you are a software engineer and you can’t even afford new shoes?

What’s wrong with looking to reduce demand for new goods and not throwing your money out the windows?
