Description
- 1. Field of the Invention
- The present invention generally relates to felt footwear soles having improved traction and more particularly to felt soles having improved traction for use on wading footwear.
- 2. Description of the Related Art
- It has been a long-standing problem that shoes and boots need to have the best grip possible so that the user can travel over rough and or slippery surfaces without loosing footing. One of the areas in which this has been most necessary is for fishermen, who are often stepping on submerged rocks, which have been made smooth by the flow of water and have been made additionally hard to stand on due to a layer of algae or slime that can form upon the such objects within a stream as well as the rock portions of the streambed itself.
- Various methods have been employed to enhance the traction of boots, shoes, and sandals, especially for purposes of fishing and other water sports. The fishing footwear referred to can be fishing waders, which comprise boots attached to pants that typically extend to mid-thigh or chest. Other fishing boots are approximately ankle high boots that are worn on the outside of waterproof stocking foot waders. Likewise, fishing sandals can be worn over these stocking foot sandals. The water proof waders can extend to mid-thigh, waist, or chest. Additionally, these types of wading footwear can be worn along without waders. Footwear for fishing has attempted to increase the traction for the user by having a sole made of flat surfaced felt. The felt has many fibrous connections which are thought to be the basis for the greatly increased the traction on slippery surfaces.
- Another traction type sole is a polymeric sole having a high traction imprinted or molded pattern on the surface of the sole of the footwear. This can be in the form of ridges, grooves, protruding nubbins or blocks, or any number of surface textures built into the bottom of the sole of the footwear. Also known are polymeric materials for forming soles having gripping characteristics of rock climber shoes with a traction pattern imprinted on them. All of these attempts to improve the traction of the wading footwear are useful, but further increase in traction is needed.
- Still another attempt at increasing the traction of footwear is to have a material that is harder than the footwear sole surface protruding from the footwear. This can be by screw-in metal studs or by metal protrusions that attach to the sole in some way. Metal protrusions or studs can increase traction in situations, but in other situations actually reduces traction. A better all around traction providing sole is still needed.
- The present invention provides advantages and alternatives over the prior art by providing a sole for water sport footwear, particularly wading footwear, and the like which is especially useful for walking on slippery surfaces without the need for studs or special formulation polymeric sole compositions.
- According to a further aspect of the present invention there is provided a felt footwear sole having a traction pattern for improving traction without the need of sewing multiple pieces to form a complete sole.
- According to yet another aspect of the present invention there is provided a felt footwear sole having a traction pattern for improving traction that may be attached to footwear using standard felt sole attaching means.
- According to still another aspect of the present invention there is provided a felt footwear sole having a traction pattern molded into the felt for improving traction that may be attached to footwear using standard felt sole attaching means.
- The present invention thus advantageously provides a one piece felt traction sole for attaching to footwear using known felt sole attachment technology and which further may be attached to a flat mid-sole or attached to a mid-sole having a heel elevation.
