Trying to mythbust here....
I grew up being told (one of those "they say" things) that you need to retire heavily-used athletic/walking shoes and get new ones fairly often because the soles lose their elasticity, flexibility, bounce, whatever. So as a young adult, I moved my sneakers along every year or so even if they seemed to be in decent shape.
Now that I'm older and question those "they say" things (who are these people anyway??? my mother quotes them all the time), I'm wondering if there's any truth to the shoe thing, or if it was just a well-played marketing ploy by shoe companies to get you to buy replacements all the time.
I'm curious because I'm looking ahead to my Switzerland/Venice trip next year. All this past summer, I've been wearing the perfect combination of shoes for my trip. I've worn the same 2 pairs of shoes all day, every day, since the snow melted, and they're awesome (a pair of Keene Kaci flats and Aetrex Lynco flips -- and yes, I know lots of people holler about flips flops for travel, but I wore them all over southern Spain last April and my feet were happy!).
So I have the perfect shoes... But I'm on my feet all day -- my phone tells me I average >10,000 steps a day, and it spends a lot of time on a shelf -- and now my perfect travel shoes have logged a lot of miles. Now, normally my shoes wear out after a season; something will rip on the uppers, or the sole will wear down, or the seams will start unraveling, but these are both in great shape. I'll continue to wear them around home and barn until it's too cold (uh, Saturday in the case of the flips) or too snowy (hopefully at least November).
My dilemma is, do I buy new pairs of these shoes soon and break them in before my trip next year because "they say" the soles on the old ones are losing their bounce, or do I keep my well-broken-in pairs over the winter and throw them in the suitcase when it comes time to travel?
Do you retire your walking shoes because they WILL become uncomfortable, or do you retire them WHEN they become uncomfortable?
(I'm pretty sure I'll just keep the old ones, but I'm curious about what other folks do)
