Just spotted a store on ebay selling a pair of Loake Buckinghams in blue.
Factory seconds, but blue is not currently listed as a colour for the Buckingham.
Something coming down the pipeline?
Theres certainly nothing in the pipeline for spring summer 2016 as Ive seen the new styles.
The likelihood is that this is a sample pair commissioned by a retailer. It's odd though as Loake do not make any shoes in blue calf leather and generally (I could be wrong) any MTO styles are limited to the materials and lasts they already have in use.
