Abstract
A sole structure may include multiple macrolayers. Each of those macrolayers may include a spring plate and a layer of damping material. Macrolayers may be bonded or otherwise fixed relative to one another and provide constrained layer damping in response to impact forces occurring as a result of activity of a wearer of an article of footwear incorporating the sole structure.
Claims5
A method, comprising:
- forming a first macrolayer by bonding a first spring plate and a first damping material layer covering at least a portion of an upper surface of the first spring plate to one another;
- forming a second macrolayer by bonding a second spring plate and a second damping material layer covering at least a portion of an upper surface of the second spring plate to one another;
- and
- bonding the first and second formed macrolayers to one another such that an upper surface of the second damping material layer contacts a lower surface of the first spring plate.
