Rollerblade Zetrablade Men's Adult Fitness Inline Skates, Black/Silver, US Men 11

Q: Can you use them on asphalt?

Yes these skates come with wheels that are good for asphalt and concrete. Keep in mind that all wheels do wear down, just like with cars you will need to rotate and eventually replace the wheels. When the time comes to replace them you can upgrade the wheels to the Rollerblade® Hydrogen wheels that will make the Zetrablade skate like a $200 skate. Wheels are one of the most important components. Please let us know if you have any other questions. https://www.rollerblade.com/usa/contact-us/

Q: Do these come with any extras like a wheel tool and or cones?

This skate comes with an Allen wrench for rotating and replacing your wheels and a short bolt in case you want to remove the brakes. Please let us know if you have any other questions. https://www.rollerblade.com/usa/contact-us/

Q: do they run big or small

This run true to size. If you are in a size 10 mens shoe then these size 10 Zetrablades will fit well. Please let us know if you have any other questions. https://www.rollerblade.com/usa/contact-us/

No only on the Right skate. You can move the Brake to left foot if you prefer. All the tools, hardware and instructions come with the skates. Please let us know if you have any other questions. https://www.rollerblade.com/usa/contact-us/
