Thank you, kind stalker

I received a mysterious envelope in the mail a while back. It it was a Visa gift card.  The only indication of who sent it was a name at a company email address.  I have never heard of this person, nor the company.  Firstly, I'm a little creeped out that someone was able to send something to my home address, which I seldom disclose.  But after a while, hey it's a free gift card, right?  I'm not sure why it was sent to me, how they found me, or who they really are, but thanks, Mr. Kind Stalker.

Today, I set out to spend the gift card.  Might as well honour a gift, right?  So I wanted shoes.  And oh my, did I find shoes.  I came out with three pairs actually.  The trouble is that I don't think I'll keep all of them- I need to decide on a pair!  And the new trouble is that none of them fit perfectly, so I'm trying to test my threshold for pain.  I think an exchange of sizes is definitely called for. 

I'm in love with the silver pair because of its uniqueness, I adore the camel colour because it's classic, and I've been searching for a bright red pair like that for quite some time.  So you see, I have a certain attachment to all of them.  Help me decide which colour to keep!
