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.

very comfortable
I ordered the same size as my old shoes from a different manufacturer and these Shimano shoes were too small. I returned and moved up a size and these are perfect. The boa allows for perfect adjustments. Very comfortable.

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.

Comfortable fit
Have ridden as far as 158 miles along with a couple other century rides in the past month since ordering these shoes to go with my Shimano Ultegra pedals. They've work great. No numbness or discomfort at all on the long rides. Had mountain bike pedals and shoes on my road bike before this so the switch has definitely resulted in more efficiency and faster ride speed. I commute daily in these and go for long rides on weekends. Also for road shoes, the heal allows for walking without too much risk of slipping, etc. Would definitely order these again when they wear out.
