Blundstone takes the tried and tested structure of the 500 Series and includes a premium leather liner for added comfort. The 587s are easy to slip off and on using the re-inforced pull-tabs and come with a shaped comfort footbed that is fully removable.  Dual-density, injection-molded polyurethane outsole and EVA footbeds team with Poron XRD inserts at the heel, helping to absorb shock and ensures all day comfort.
