Memory Foam is a type of high density synthetic material designed to provide support and protection.
Memory Foam conforms to the pressure of weight or heat and has the property to return to its original shape after the pressure is released.
About Spikes:
Spikes are specifically made shoes that have small metal (or other material) spikes on the sole of the shoe. The Spikes have a small diameter (Cleats are larger knobs on the soles and a Cleat could be a group of Spikes). Spikes are common on Golf Shoes because the spikes help with traction in grass. Runners also may use Spikes for the grip with the ground when running.
