I made this resolution years ago, but it requires planning.
For one thing, you have to throw away a lot of old socks to do this.
You then have to decide on a new sock and buy a lot of them *all at once.” Hanes changes the design on their ankle white socks constantly so 2017s don’t match 2018s. Often the difference is large and glaring. And best to do in store, because Amazon can mix products together in one listing. Or will have a mix of old and new stock.
Then there is the winter/summer issue. I wear thicker Wigwam socks in the winter and thinner hanes the rest of the year.
