Shoestring with gripping regions

Abstract

A shoestring made from elastically deformable silicone defines a constant taper between opposite end portions and a center portion, is narrowest at the center portion, and increases in size in an axial direction between the center portion and each end portion. The center portion may be configured with a length which is approximately one half of the total length of the shoestring. The end portions may each be configured with a length which is approximately one quarter of the total length of the shoestring. Each end portion may also define a convex end with a tapering cross-section in an axial direction away from the center portion, and may be colored differently than the center portion.

Dependencies are inferred from the claim text.
