Create your own shoe Somnio Running, a new company in Santa Cruz, Calif., touts its upcoming line of footwear as the world's first "truly customizable" running shoes.

The company's system will include three shoe models; three types of footbeds; cushion inserts with differing densities for the heel and forefoot areas; and wedge inserts made to help align the foot and lower leg. When mixed and matched to a runner's foot in a store, these components can create 648 unique shoe types.

Arch comfort, leg alignment, cushioning and pronation control are among the benefits a Somnio (www.somnio running.com) customer might find.

The shoes, available in May, will be sold at independent running shops. Prices will start at about $125 per pair.
