The second most popular model throughout the world. Famous under other brand-names - this is the improved and upgraded version of an R-Class legend.
The RC40 has more volume in the box and less volume in the heel than the RC30.
The previous generation of this shoe was only available in a soft shank with a microfiber tip. Now you can choose between a satin tip and microfiber AND all three shanks which all have a 3/4 component.
