Abstract

A hiking shoe includes a vamp connected to an outsole. Multiple anti-blocks are formed on the underside and multiple spikes are respectively embedded in the anti-slip blocks that are located between the rear section and the front section of the underside of the outsole. Each spike has an end face that is formed on the first end thereof, and the end face is in flush with the distal end of the anti-slip block corresponding thereto. The second end of each spike is located within the anti-slip block corresponding thereto. The end face of each spike has multiple grooves defined therein so as to provide better anti-slip feature when walking on a wet path with pebbles.

Description

BACKGROUND OF THE INVENTION

1. Fields of the Invention

The present invention relates to hiking shoes, and more particularly, to hiking shoes with anti-slip spikes embedded in the outsole.

2. Descriptions of Related Art

There are many different types of hiking shoes that have different features for different trail conditions. Most of the trails in the forests have pebbles which can make conventional hiking shoes fail to protect the wearers because the pebbles reduce friction between the hiking shoes and the paths of the trails, especially in rainy days. Some hiking shoes have spikes protruding from the outsole such that the spikes bite into the soil and provide better friction. However, theses spikes cannot perform as desired because pebbles rolls and small in size, spikes cannot penetrate through the pebbles to grab the shoes in the trail paths. The pebbles are easily stocked between spikes to affect the effective length of the spikes so that the spikes cannot bite into the soil.
The present invention is intended to provide a hiking shoe that has anti-slip blocks and spikes are embedded in some of the anti-slip blocks. Each spike includes grooves in the distal face thereof to provide better anti-slip features.

SUMMARY OF THE INVENTION

The present invention relates to a hiking shoe and comprises a vamp that is connected to the outsole. Multiple anti-blocks are formed on the underside of the outsole, wherein the underside includes a rear section and a front section. Multiple spikes are respectively embedded in the anti-slip blocks that are located between the rear section and the front section. Each spike has an end face that is formed on the first end thereof, and the end face is in flush with the distal end of the anti-slip block corresponding thereto. The second end of each spike is located within the anti-slip block corresponding thereto. The end face of each spike has multiple grooves defined therein.
Preferably, the front section of the underside of the outsole includes a first area and a second area, and a bending line is defined between the first and second areas. The benign line is formed when the wearer lifts his/her. The anti-slip blocks that are located on the bending line each have one of the spikes.
Preferably, each of the spikes includes a head and a shank. The outsole includes recesses which are located corresponding to the spikes. The recesses are defined through the outsole and the anti-slip blocks corresponding thereto. Each recess includes a large-diameter area and a small-diameter area, wherein the small-diameter area is located in the anti-slip block corresponding thereto. The large-diameter area is defined in the outsole, so that the head of the spike is engaged with the large-diameter area corresponding thereto, and the shank of the spike is located in the small-diameter area corresponding thereto to prevent the spike from dropping off from the recess.
Preferably, the rear section of the underside of the outsole includes a third area and a fourth area, and a separation line is defined between the third and fourth areas. The spikes that are located in the rear section are located close to the separation line, and the fourth area has no spike located therein.
Preferably, the third area includes a flat section and a curve section. One of the anti-slip blocks in the curve section has one of the spikes connected thereto. The spikes that are located in the flat section and the spike that is located in the curve section are located at three points of an imaginary triangle.
The advantages of the present invention are that the spikes are arranged in the first, second, third and fourth areas so that the groves of the spikes contact pebbles on the trail paths and provide sufficient friction.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 7, the hiking shoe 1 of the present invention comprises a vamp 11 and an outsole 12, wherein the vamp 11 is located above the top of the outsole and connected along the periphery of the outsole. The vamp includes an opening 14 and a trim portion 15 which is located along a portion of the opening 14. The opening 14 is configured to accept insertion of wearer's foot. The outsole 12 includes an underside 13, and multiple anti-blocks 16 are formed on the underside 13 and located at a distance from each other. The underside 13 includes a rear section 131 and a front section 132.
Multiple spikes 2 are respectively embedded in the anti-slip blocks 16 that are located between the rear section 131 and the front section 132. Each spike 2 has an end face that is formed on the first end thereof; and the end face is in flush with the distal end of the anti-slip block 16 corresponding thereto. The second end of each spike 2 is located within the anti-slip block 16 corresponding thereto. The end face of each spike 2 has multiple grooves 21 defined therein. Preferably, the grooves 21 are in a netted pattern. When the hiking shoes 1 step on rocks or pebbles, the grooves 21 provide sufficient friction and anti-slip feature.
Specifically, as shown in FIG. 3, the front section 132 of the underside 13 of the outsole 12 includes a first area 1321 and a second area 1322. A bending line “A” is defined between the first and second areas 1321, 1322, and the benign line “A” is formed when the wearer lifts his/her heel. The anti-slip blocks 16 that are located on the bending line “A” each have one of the spikes 2. The rear section 131 of the underside 13 of the outsole 12 includes a third area 1311 and a fourth area 1312. A separation line “B” is defined between the third and fourth areas 1311, 1312. The spikes 2 that are located in the rear section 131 are located close to the separation line “B”, and the fourth area 1312 has no spike 2 located therein.
It is noted that each of the spikes 2 includes a head 22 and a shank 23. The outsole 12 includes recesses 121 which are located corresponding to the spikes 2. The recesses 121 are defined through the outsole 12 and the anti-slip blocks 16 corresponding thereto. Each recess 121 includes a large-diameter area 122 and a small-diameter area 123. The small-diameter area 123 is located in the anti-slip block 16 corresponding thereto, and the large-diameter area 122 is defined in the outsole 12. The head 22 of the spike 2 is engaged with the large-diameter area 122 corresponding thereto, and the shank 23 of the spike 2 is located in the small-diameter area 123 corresponding thereto so as to prevent the spike 2 from dropping off from the recess 121. The third area 1311 includes a flat section 133 and a curve section 134. One of the anti-slip blocks 16 in the curve section 134 has one of the spikes 2 connected thereto. The spikes 2 that are located in the flat section 133 and the spike 2 that is located in the curve section 134 are located at three points of an imaginary triangle.
When the rear section 131 contacts the trail path, the rear section 131 has the maximum contact area with the trail path, so that the multiple spikes 2 are arranged in the third area 1311 and located close to the separation line “B” can obtain the best anti-slip feature. Furthermore, when the heel of the hiking shoe 1 is about to lift and the front section 132 of the hiking shoe 1 is about to contact the trail path, the spikes 2 on the rear section 131 prevent the wearer from slipping if the rear section 131 contacts pebbles. The spike 2 located at the curve section 134 ensure the walking in a stable status. The spikes 2 that are located at the three points of the imaginary triangle can ensure at least one spike 2 to contact the trail path in any situation.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
