They are very springy when you walk, so it makes it easy on your legs when walking as well. Wish it came in different colors. so many a tips at a great price and the pink is really cute I do recommend reviewing how big this actually is before purchase just to make sure it is what youre looking for in size, but it is a great product honestly. I?ve had no problems though. The bike sensor functions as it should and additional data is helpful but the sensor fell off during a ride and the mounting boot that the sensor sits in as lost. They are practically ancient in the world of technology (okay they are ancient in the world of technology) but I really dont want to buy another ipad yet. For the price, you get your moneys worth and very comfortable to use. I cant say enough about how fast they were shipped. Lost my original pair.
