Vexes are an original idea of a interchangeable soccer cleat, to allow people to only need one cleat to play both indoor and outdoor soccer. Normally people would end up paying hundreds of dollars to get 2 separate pairs of cleats, but now thanks to vexes you only need one pair for both indoor and outdoor. Vexes utilize a simple and unique design that allows the outside cleat become an indoor cleat. All you do is in slide the indoor cleat bottom over the pegs and you are ready for the court. Take off the indoor cleat and you are ready to take on the pitch.
Here are pictures of the prototype for the bottom cover for the cleat which can be put on over the studs of the outdoor cleat.
Currently, the only competition being faced by VEXES are the Adidas Glitches. The Adidas Glitches are the closest thing to VEXES on the market; however, Glitches are designed for a different type of need and customer. While Glitches are interchangeable, they only change the type of cleat to correspond to the length of the grass of the pitch that is being played on and for cleat customization. VEXES are designed to go from indoor cleats to outdoor cleats and vice versa, VEXES are clearly the better choice for the targeted customer.
