If size do not feet, or if u are are not happy with what get, please find email invoice you get from shop, where you have made order and ask that shop for address where you should ship goods back. When you contact them, please use your order number from email invoice from your order (not Paypal transaction number), so support of that shop knows about what order your are talking about.
If you will have any problems with support of some shop, please email me to post@shoespost.com
Thank you
