Ultralon Foam.

Ultralon Foam is a space-age material that provides advanced heat moldability with unprecedented levels of comfort and fit. Our Ultralon F.I.T. liners use a mixture of two different densities of Ultralon Foam to create a liner that is simultaneously resistant to packing out and insanely comfortable. The inner layer is plush and cozy, so your feet always feel snug. The second layer provides maximum support, heat moldable customization and performance to the boot.
