How long does a pair of socks last
Short answer: Six months to a year and a half with daily wear. Toe and heel go first, and rotation extends the life the most.
What wears out
Almost all wear happens under the heel and over the toe. There the fabric is pressed against the shoe with every step. Those two places therefore decide when a sock is finished.
Rotation makes the big difference
Four pairs in rotation last more than twice as long as two. The fibres recover between wears and each pair is washed less often. See bamboo socks for men.
Shoe and nails count too
A hard edge in the shoe or an overlong big toenail wears a hole in the same spot every time. Check both before blaming the sock. See all bamboo socks for men and bamboo socks for women.
Frequently asked questions
Can a hole in the toe be darned
Yes, with a darning needle and yarn of similar weight. It holds well on small holes.
Why does one sock go before the other
Because most people have one slightly larger foot and a different gait on one side.
Are thicker socks more durable
Not automatically. A reinforced toe matters more than thickness alone.
