Custom designed and co-branded Esquivel for Blackbird boots. Made from natural, untanned leather. Within weeks each pair is going to age and darken through wear, exposure to sunlight, and overall how they are treated by the wearer. Completely hand made in the USA in a process which takes over one hundred steps to complete followed by another two weeks to allow for each shoe to dry naturally on their last/mold to ensure that they perfectly retain their shape. Sizing runs about a half size large. Sold exclusively at Blackbird.
