I also remember looking at some backpacks in another sporting goods store.
Just now, my phone goes blip (notification of email). I click on gmail and it's just another "just for you" email from ebay.
No big deal, I get them regularly.
One thing to consider is that if you're looking for hiking boots or sandals, you'll probably also be considering a backpack. Or at least there will be some statistical correlation in that they are often bought together.
Did you go into these shops because there was a promotion on these products? Or they were displayed prominently in the shop window? It could be that your movements were tracked to these shops which also had on-line promotions and maybe there is some service for targetted advertising which uses this data and informs their clients what you are most likely going to respond to.
I had an interview at a company last year in Edinburgh which were working on tracking where people were in shopping centres for exactly this kind of reason,.
