This is the go-to place for Blundstones. I called the Australian Boot Co. because of split soles in my 10 year old Blunnies (I thought they'd NEVER wear out), and they recommended Nick's.
For 85 bucks all in, they re-soled them in a week, and they did a great job (see pics). He (Nick?) told me "if ANYthing goes wrong, bring them back ANY time".
(They also make boots here. They'll duplicate any pair you want from a picture.)
