Description The RP4 from Shimano features a high-performance design that's catered to endurance riders -- showcasing a blend of competition-optimized designs and comfort and efficiency-enhancing features. To ensure durability and conformity, this shoe is constructed of a supple, high-density synthetic leather. Strategically located perforations along the sides, at the tongue, and above the toes provide ample ventilation. The lightweight glass fiber reinforced nylon sole facilitates efficient power transfer from shoe to pedal. Anatomically precise offset straps help relieve tension at the highest point of the foot, where pressure tends to be greatest. For a secure fit and quick yet precise adjustment, the RP4 features the micro-adjustable Boa® L6 dial.

Super comfy
This is my first venture into BOA laced shoes. Now I know what they mean that once you try BOA shoes you will never go back. Equal pressure all the way around the feet with no hot spots. These shoes are so comfortable its like riding with slippers. I love the jet black color. I have only worn carbon soles shoes for the past ten years or so. The fiber glass sole on these shoes are stiff enough. I could not tell a difference. I've been having problems with my feet lately and tried different things such as insoles and different pedalscleats. These shoes solved the problem. First pain free ride in a couple of months. I can't say enough about these shoes. They fit a little snugger than my other Shimano road shoes, but not too tight. The toe box is more rounded. Excellent value. Biketiresdirect has the best price on the web for these shoes with free shipping.
