[[SPOILER]] In April I had C&J NYC change my dark brown cordovan Harlech's from double leather to Ridgeway soles. Cost was $210 total, which included mailing both ways. It took about 6 weeks and was very easy. If I remember correctly there was no tax, and because the boots are going back to the UK for repairs there are no import/export duties and fees.
