Don't know where else to put this. I rarely ever wear work boots and don't like to but with this weather and my snow/ice removal the last two days, I've worn my 10+ year old Wolverine boots that fit well and do the job. For about two weeks I've been getting ads on Facebook about boots. LONG before I even thought about using them for this weather. Yesterday I noticed my heel getting wet and when I took them off, the sole was separated from the leather, today, both soles are separated. Blows my mind, I never even thought of boots but I'm getting ads because I need new boots now and today I got an ad for larger sizes with wide EEEE sizes, which is what I wear. How does an algorithm figure this out?
