When I learned they had Boston and Chicago socks, I started stalking the website until they came out with the no-shows. I then emailed and found out the mini-crew socks were coming in a few days. At that point, I created an account and then shared the Feetures referral link on tons of NYC Marathon pages. I got over nine referrals but learned after that you can't combine the $10 vouchers so I wasn't able to actually get free socks. Instead, I got $10 off one purchase and still have nine more $10 vouchers.
I can't wait for these to arrive and hopefully, if I get at least one trial run in with them before November 7th I can wear them for the marathon. Otherwise, I'll wear my other Feetures which are just gray for the marathon and save these for the next event.
