Can I transfer the VKs from one pair of shoes to another?
Yes, if they are the same shoe type. In other words, if you bought VKs for a cleated shoe, it's ok to move them to another cleated shoe. If you bought for a non-cleated shoe (eg-basketball), not a good idea to try to fit them into a soccer cleat. If you are moving the VKs, try to take them out by slipping your fingers under the carbon fiber plate - and not by pulling up on the foam, which can damage the VK.
