I have shoes that I only use in my basement to go on my treadmill and stationary bike. The shoes have red soles. Yesterday while stretching I looked down at my treadmill and I saw two red lines on the track belt where my feet land when running.

They are a bit hard to see in the photo despite playing with the colour contrast, but they are quite visible when I look for them on the belt. I don’t know why, but it didn’t occur to me that I would be wearing down the treads on my shoes just running on a treadmill. Thinking about it now, it does make sense. I’ve been using these same shoes for five and a half years… of course they would have some wear and tear as I walk and run on a treadmill 4-6 times a week.

But had my soles not been red, leaving their marks on my treadmill, I probably would have ignorantly ran in the same shoes for another 3-5 years without replacing them. It’s funny how we take objects for granted, expecting them to work, not thinking about repairing or replacing them until they just don’t work anymore.

You aren’t likely to replace a kettle or toaster until it stops working. Your favourite jeans remain your favourite until they tear. That 5,000 hour light bulb was not something you ever thought would need replacing until it just doesn’t turn on.

While our bodies age and show signs of wear and tear, we don’t always think about other things that do until a repair or replacement are needed. But these worn down shoes can actually affect my stride and cause me issues before I realize they need to be replaced. They can affect my personal wear and tear.

What’s something you just expect to work until suddenly it doesn’t anymore?
