Definitions

  • the present invention relates to a detachable toe protector for sports shoes, particularly for run- ning shoes. More particularly, the present invention relates to a toe protector for cross-running shoes.
  • Runners, particularly off-road runners usually require toe protection of their running shoes as they usually get injured from their toes due to striking the ground, or any protrusions on the ground (stone or the like) with toe parts of their shoes.
  • the toes are usually best protected by safety shoes provided with a protective cap made of steel, aluminum or high-strength plastics at their forepart in order to protect the toes against injuries resulting from heavy falling objects.
  • Safety shoes of this kind are not suitable for athletes as the weight of the material used imposes extra load which may negatively affect the physiology, balance of the feet and body of athletes.
  • Protective toe caps which cover substantial part like all forefront of one foot are also not suitable for athletes as they affect the function of the shoes which are suitable for running.
  • Main function of above mentioned protective toe caps is protecting the feet of one standing user against being grievously injured from falling or crushing objects.
  • These protective toe caps do not adequately dampen the soft tissue injury caused by crushing the toes against the inner wall of the toe cap resulting from the user himself or herself striking an object while in a running (slow) motion with a high momentum (e.g. 150-1000 kg-m/s).
  • Primary object of the present invention is to eliminate the above-mentioned shortcomings of the toe protectors in the prior art and to provide a toe protector suitable for sports shoes, particularly for running shoes.
  • Primary object of the present invention is to eliminate the above-mentioned shortcomings in the prior art.
  • the present invention is related to a detachable or built-in toe protector for a sports shoe, comprising a perimetric body which is formed arcuate, the perimetric body comprising a front wall 30 having a concave inner face shaped to fit on the toe part of the shoe or to accommodate a user's toes, the perimetric body extending from the front wall along the peripheral edges of the left and right hand sides of the shoe or along the lower side edges of the shoe, the perimetric body provided with attachment means to prevent the toe protector's unintended disengagement from the shoe, characterized in that the front wall being formed of multiple layers having at least one impact-absorbing layer and at least one cushioning soft layer.
  • Figure 1 is a top view of the toe protector according to the present invention.
  • Figure 2 is a perspective view of a cross section of the toe protector according to the present invention.
  • Figure 3 is a side view of one side wall of the toe protector according to the present invention.

  • the perimetric body 20 is completely open across its bottom and in permanent contact inwardly with the front part of the shoe.
  • the front wall 30 of the perimetric body 20 is designed to protect the toe part (tip) of one foot in a shoe. Accordingly, the front wall 30 generally covers the surface of the toe part (tip) of one shoe and reaches substantially to the sole part (as opposed to the "upper") of the shoe on the sides.
  • the front wall 30 has a concave inner face shaped to fit on the toe part (tip) of the shoe.
  • the two side walls 40, 50 of the perimetric body 20 are designed to extend from the front wall 30 along the peripheral edges of the left and right hand sides (lateral edges) or along the lower side edges (sole part) of the shoe.
  • the inner faces 41, 51 of the side walls 40, 50 are shaped to fit snugly on the peripheral edges of the left and right hand sides (lateral edges) of the shoe.
  • the perimetric body 20 of the toe pro- tector 10 is constructed as having a thick cross-section at the front wall 30, which decreases grad- ually towards the peripheral edges of the left and right sides (lateral edges) of the shoe and forms the side walls 40, 50.
  • the extension of the perimetric body 20 exceeds metatarsophalan- geal (MTP) joint of the foot wearing a shoe comprising the toe protector 10 of the present invention.

  • the toe protector 10 is constructed as having a thick cross-section at the front wall 30, which decreases gradually towards the side walls 40, 50. Accordingly side walls 40, 50 have thinner sections relative to the front wall 30, so the toe protector 10 is comfortable to the user of the shoe.
  • the toe protector 10 of the present invention has a length (L) at the front wall 30 as to cover the toe part of the shoe, which decreases gradually towards the side walls 40, 50. Accordingly side walls 40, 50 have shorter lengths relative to the front walls 40, 50 so the toe protector 10 is comfortable to the user.
  • the length of the front wall LI is within the range of 10-20 mm and the length of the rear edges of the side walls L2 are within the range of 2-4 mm.
  • the two side walls 40, 50 are sufficiently flexible and resilient that can be deformed (expanded), preferably at the tips but which retain their shapes when the deformation force is removed.

  • a user can put on the toe protector 10 by stretching the side walls 40, 50 outwardly from each side of the shoe and placing the toe protector 10 under tension in its suitable position on the shoe and releasing the side walls 40, 50.
  • the resilient force of the side walls 40, 50 causes the toe protector 10 to stay firmly attached on the shoe.
  • To remove the toe protector 10 it is again only necessary to stretch the side walls 40, 50 outwardly from each side of the shoe, taking the toe protector 10 under tension away from the shoe and releasing the side walls 40, 50.

These notches get firmly dug into the lateral facets of the sole part of the shoe when the toe protector 10 is released after an expanding force is removed. This structure permits the detachment and replacement of the toe protector 10 by the user when it is worn out by impacts and becomes inadequate in terms of resilience and thus protection capacity.
