good point, you'd need a huge amount of adjustment for this product because not everyone rides with their seat directly next to their wheel

Do you not think that if your trying to get round the problem of your shoe wearing out, with the footsie its going to either; - wear down your tires very quickly (similar to the way it wears down scooter wheels) therefore will cost your a lot of money in the long run - or depending on the material of the product its going to wear down the footsie itself, therefore you will have to keep replacing the product over and over again. Either way its going to cost you more money in the long run than if you were to just buy a brake
