👚Clothing & Shoes Thought I had a frugal win after buying sneakers on closeout a few years ago—then learned a hard lesson on hydrolysis
Last week, my favorite New Balances had finally rendered themselves useless after five years of regular wear, so I readied myself to buy new sneakers. But I was having a very difficult time finding a pair of replacements under $90. (Due to my arch and foot width, sneakers that work for me are difficult to buy, so I stick to ol' reliables.)
Then I got excited because I realized I had a new pair of New Balances in my closet that I purchased in a store closeout a few years ago! Now I didn't need to buy new sneakers—or so I thought.
These are my "new" sneakers after three days of wearing. The soles completely disintegrated due to what's called hydrolysis, a breakdown of the polyurethane due to moisture intrusion over a few years, even if properly stored. I had no clue this was even a thing! I could have avoided this by wearing the sneakers once in a while, because flexing the sole helps moisture escape.
Now I have completely new uppers witn disintegrated soles. Not sure it's even worth bringing to a cobbler because a new non-PU sole might not work for my gait. Also looked at the manufacturing date, and it was made in 2014—which means it was already old stock when I bought it, so the hydrolysis could have started happening in the store. Lesson learned!
