Check Your Shoe Size Once a Year to Avoid Discomfort
An improper fit in your shoes can cause all kinds of problems and it turns out your foot size can change over the course of a year, which is why The Wall Street Journal suggests checking your size once a year:
When was the last time you had your foot measured to check your shoe size?
If the answer is more than a year ago, there is a good chance your shoes are causing you some kind of pain, from pinched toes to unsightly calluses. Foot shape and size can change in small but meaningful ways throughout adulthood, yet time-starved shoppers increasingly order shoes online and forgo proper sizing by a trained salesperson.
When you do get your foot size checked, you're looking for a few key things. Here are some notes to keep in mind when you get your foot measured:
For pain in the heel, known as plantar fasciitis, choose shoes that have proper arch support and sole cushioning
Use a Brannock Device (that metal measuring device at shoe stores) to measure the length and width of the foot and the length of the arch. Shoe size should be a guide, not an absolute. Go with what feels most comfortable.
The ball of the foot is its widest part. if you are unsure about a shoe's fit, outline the sole on a piece of paper and place your bare foot inside to check if it spills over.
Shoes should be a thumb's width longer than the longest toes. If too narrow, shoes can cause a bunion; if too short, they can lead to a hammertoe.
Most importantly, it's just good to keep in mind that you probably don't have a set shoe size. So, even if you tend to shop for shoes online, it's probably good to get a measurement about once a year (preferably in the afternoon), and keep the above tips in mind when you get the shoes in the mail.
