The best $90 I ever spent was on my feet.
I walk an average of 2.3 miles a day, which is on the low end for a typical New Yorker. Still, that's a considerable amount, especially when you're wearing uncomfortable shoes to work.
For a while, I wore heels that pinched or unsupportive flats as I scaled subways stairs and navigated cracked sidewalks. When I had room in my bag, I brought a back-up pair to change into, but lugging footwear around was cumbersome.
I thought about how much I do on my feet everyday: commuting, coffee meetings out of the office, after-work appointments. And I asked myself: Why not invest in a pair of shoes that will make me feel and look great at my job?
