A method for managing memory among virtual machines in a system having a plurality of virtual machines, includes providing at least one memory optimization mechanism which can reduce memory usage of a virtual machine at a cost of increasing CPU usage. The strap is attached to the foot so that the electrodes are positioned to stimulate with an electrical signal the abductor hallucis muscle of the foot to correct an imbalance due to overpowering by the adductor hallucis muscle in the large toe. An aluminum foil is then laminated to the heat sealable able layer of the interlayer.
