Aline footbeds are easily the best generic footbed on the market today. I've been using them personally for over 10 years now and use them in my ski boots and all my cycling shoes not to mention when I hike or when I ice or inline skate. I supply them for my riding cohorts and support young bike racers here in Detroit you generate more power into their pedal stroke. In ski boots, Alines cure most problems that appear in boot fitting scenarios. By creating a more secure and better align fit not only do skiers perform better, generate better turns, but are safer due to a more secure and complete fit at the body's primary interface to the planet, the bottom of the foot!
