I highly doubt that Allen Edmonds would use removable insoles in their general line of footwear. I know that some of their "comfort shoes" and "golf shoes" do, but by and large, they use a leather and cork footbed (which is integral to the shoe's construction) as shoemakers have done for a few hundred years. Such construction prevents boot stink, allows for proper support of the foot (news flash: cushion and support are mutually exclusive in most cases), and makes for a sleeker profile (never a bad thing, in the opinion of most shoe-lovers). Go for it... just be prepared for the quality shoes to multiply.
