I bought the Londons in Iron and the leather is a really good grey.  The oiled leather distresses with wear making, very cool patina. I think they look more like a short boot and the leather is more stylish than other Londons I have had.  I have worn them on many an evening in the city for casual events with long skirts or jeans.

The Londons -Hunter Black took a week to break in, the leather is strong but pliable. I've had that style for years.  The London's in Iron Oiled Leather took 2 months to break in, because the leather is thicker and holds its' shape a bit better.  Now they are almost as comfortable as the hunter black.  Comparison: the hunter black/brown Londons are more comfortable, the iron oiled leather are cooler.

I have been conditioning the leather with Meltonian Boot & Shoe Cream Polish per my cobbler's advice.  It works great and does not darken the leather.
