The colours available for Linings are; Red, Black, Natural, Dark Green, Dark Brown, Navy Blue, Electric Blue, and possibly limited time only, Orange.
Red is probably the most popular choice.
I also forgot one detail Matt.
Binding, fitted to the edges of the Facings?
I might suggest Black to run with the commando Sole in Black. There are no Red Options for Binding, only Tan, Brown White, Navy Black etc.
