Boot with increased stability

Abstract

A boot includes an outsole having a bottom surface configured to contact the ground, and a baseboard configured to support a wearer's foot and having an upper surface defined by a forefoot portion, an arch portion, and a heel portion, the upper surface of the baseboard defining an outer perimeter. When the boot is at rest on a flat surface, a maximum height of the heel portion of the baseboard above the flat surface is smaller than a maximum height of the arch portion of the baseboard above the flat surface. The boot can include an upper secured to the baseboard at or below the outer perimeter of the upper surface of the baseboard, and a footbed having an upper surface configured to contact a wearer's foot and a lower surface that substantially matches the upper surface of the baseboard.

1 . A boot comprising:
 an outsole having a bottom surface configured to contact the ground; and   a baseboard configured to support a wearer's foot and having an upper surface defined by a forefoot portion, an arch portion, and a heel portion, the upper surface of the baseboard defining an outer perimeter,   wherein when the boot is at rest on a flat surface, a maximum height of the heel portion of the baseboard above the flat surface is smaller than a maximum height of the arch portion of the baseboard above the flat surface.   
     
     
         2 . The boot of  claim 1 , further comprising an upper secured to the baseboard at or below the outer perimeter of the upper surface of the baseboard. 
     
     
         3 . The boot of  claim 1 , further comprising an upper secured to the outer perimeter of the upper surface of the baseboard at the arch portion and at the heel portion. 
     
     
         4 . The boot of  claim 1 , further comprising a footbed having an upper surface configured to contact a wearer's foot and a lower surface that substantially matches the upper surface of the baseboard. 
     
     
         5 . The boot of  claim 4 , wherein a side surface of the footbed extending between the upper and lower surfaces thereof substantially matches an adjacent surface of the upper. 
     
     
         6 . The boot of  claim 1 , wherein the outsole is comprised of a treadsole configured to contact the ground and a midsole configured to contact the baseboard. 
     
     
         7 . The boot of  claim 6 , wherein the treadsole and the midsole are comprised of different materials. 
     
     
         8 . The boot of  claim 7 , wherein the baseboard is more rigid than the treadsole, and the treadsole is more rigid than the midsole. 
     
     
         9 . The boot of  claim 1 , wherein the baseboard is comprised of a polymer. 
     
     
         10 . The boot of  claim 9 , wherein the polymer is nylon. 
     
     
         11 . The boot of  claim 1 , wherein the entire baseboard has a substantially constant thickness. 
     
     
         12 . The boot of  claim 1 , wherein the upper surface of the baseboard and a lower surface of the baseboard have substantially identical shapes. 
     
     
         13 . The boot of  claim 1 , wherein the baseboard includes puncture protection in accordance with ASTM, CSA, Nom 113, and ISO safety standards. 
     
     
         14 . A boot comprising:
 an outsole having a bottom surface configured to contact the ground; and   a baseboard configured to support a wearer's foot and having an upper surface defined by a forefoot portion, an arch portion, and a heel portion, the upper surface of the baseboard defining an outer perimeter,   wherein when the boot is at rest on a flat surface, a height of the entire heel portion of the baseboard above the flat surface is smaller than a height of the entire arch portion of the baseboard above the flat surface.   
     
     
         15 . The boot of  claim 14 , further comprising an upper secured to the baseboard at or below the outer perimeter of the upper surface of the baseboard. 
     
     
         16 . A boot comprising:
 an outsole having a bottom surface configured to contact the ground;   a baseboard configured to support a wearer's foot and having an upper surface defining a forefoot portion, an arch portion, and a heel portion, the upper surface of the baseboard defining an outer perimeter; and   an upper secured to the outer perimeter of the baseboard at the arch portion and the heel portion along a continuous seam,   wherein when the boot is at rest on a flat surface, a maximum height of the seam above the flat surface at the heel portion is smaller than a maximum height of the seam above the flat surface at the arch portion.   
     
     
         17 . The boot of  claim 16 , wherein when the boot is at rest on a flat surface, a maximum height of the seam above the flat surface at the forefoot portion is smaller than the maximum height of the seam above the flat surface at the arch portion. 
     
     
         18 . The boot of  claim 16 , further comprising a footbed having an upper surface configured to contact a wearer's foot and a lower surface that substantially matches the upper surface of the baseboard. 
     
     
         19 . The boot of  claim 16 , wherein the outsole is comprised of a treadsole configured to contact the ground and a midsole configured to contact the baseboard, wherein the treadsole and the midsole are comprised of different materials. 
     
     
         20 . The boot of  claim 19 , wherein the baseboard is more rigid than the treadsole, and the treadsole is more rigid than the midsole.
