Open-Sole Combat Boot with Arcuate Vamp for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boot devices for combat sports do not adequately protect feet and legs from kicks while allowing for free movement and impact absorption during both receiving and delivering kicks.
Innovation Solution
A pair of boots with a substantially open sole and open calf design, featuring a concavely arcuate vamp and front quarter that wraps around the lower leg, along with a resiliently compressible pad and adjustable fasteners or straps for secure fit and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional closed boot design is used, then foot protection is improved, but freedom of movement and impact absorption are reduced
Solution Approach 1:
The boot is divided into separate functional zones: an open toe box for toe protection without enclosure, a vamp covering the instep, a quarter extending up the leg, and a sole providing base protection. This segmentation allows each zone to be optimized independently - the open toe allows natural toe movement while the quarter provides leg protection, resolving the contradiction between protection and freedom of movement.
Solution Approach 2:
Different parts of the boot have different levels of coverage and material properties. The toe box is open while the quarter extends higher for leg protection. The vamp and quarter can be made from different materials with varying degrees of flexibility and protection, allowing local optimization where protection is needed without restricting movement in areas requiring flexibility.
2Object-affected harmful factors
If rigid boot structure is used, then protection is improved, but impact absorption and comfort are reduced
Solution Approach 1:
The boot combines rigid protective elements (the quarter structure extending up the leg, protective toe box) with flexible materials (the vamp and lacing system). This composite construction provides hard protection for the shin and toe areas while allowing flexible movement and impact absorption through the softer materials, resolving the contradiction between protection and impact absorption.
Solution Approach 2:
The boot design incorporates protective elements positioned beforehand to absorb and distribute impact forces. The quarter extending up the leg and the protective toe box are structured to receive and dissipate kick impacts before they reach the foot and shin, while the overall flexible construction allows the boot to give slightly under impact, enhancing energy absorption.
3Ease of operation
If open sole design is used, then freedom of movement is improved, but protection against ground contact is reduced
Solution Approach 1:
The sole is designed as a segmented structure that provides protection where needed (heel and arch areas) while leaving the forefoot area more open to allow natural foot movement and flexion. This segmentation enables the boot to provide ground contact protection without restricting the freedom of movement in the toe area.

AI summary
A protective boot assembly for protecting feet and legs during combat sports includes a pair of boots. Each of the boots is worn during combat sports thereby facilitating a foot and a shin to be protected when receiving kicks and when delivering kicks. Each of the boots has a substantially open sole and an open calf.
