Crampons provided with spikes

A crampon system comprising:

• an elastic band adapted to be bound around an outsole of a boot, and
• a crampon comprising:
• a front spike having a plurality of first spike edges, the front spike adapted to be positioned at a front portion of a bottom surface of the boot when the elastic band is bound around the outsole of the boot;
• a center spike having a plurality of second spike edges, the center spike being coupled to the elastic band via a first chain, the center spike adapted to be positioned at a center portion of the bottom surface of the boot when the elastic band is bound around the outsole of the boot;
• and
• a rear spike having a plurality of third spike edges, the rear spike being coupled to the elastic band via a second chain, the rear spike adapted to be positioned at a rear portion of the bottom surface of the boot when the elastic band is bound around the outsole of the boot;
• a plurality of lateral spikes disposed between the front spike and the center spike, each lateral spike coupled to the elastic band via a respective third chain;
• first and second front chains disposed between the front spike and the band, each of the first and second front chains comprising a plurality of advanced front spikes connected together in a series, each advanced front spike having an L-shape comprising a first leg and a second leg, wherein:
• the first leg comprises a first surface associated with a first plane, and a hole in the first surface;
• the second leg comprises a second surface associated with a second plane different from the first plane;
• the first surface and the second surface intersect to form a corner;
• a gap is defined in the first surface of the first leg, in the second surface of the second leg, and in the corner, the gap defining a projecting element, the projecting element having a first portion in the first leg, a second portion in the second leg, and a bend in the corner, the gap being present on two sides of the first portion of the projecting element in the first leg and on three sides of the second portion of the projecting element in the second leg;
• the gap is adapted to receive an adjacent first leg of an adjacent advanced front spike;
• and
• the projecting element is adapted to connect to an adjacent hole of the adjacent first leg of the adjacent advanced front spike;
• and
• a restraining member operatively coupled to the first and second front chains, the restraining member adapted to be engaged with a front of the boot when the elastic band is bound around the outsole of the boot.
