You're probably not interested in foot size from the other side of the gender pond, but I really wonder if my feet have become a bit smaller since I started testosterone early this year.
I saw a great online deal on some ankle boots from my favorite manufacturer. I've worn a few generations of these boots and ordered my usual size. When I tried them on, they were tight, tight, tight. The boots languished in the corner for months. Then I decided to start wearing them around the house for a few hours a day until they loosened up. I put them on, and they fit perfectly. My other shoes, which fit me to begin with, are now just a tad too roomy. I have to lace them up extra tight, and that's not quite enough.
I'm always reading about guys whose feet supposedly grew on T. I'm the first one I've heard of who may have experienced the opposite. Weird.
