If The Arch Length Is Longer Or Shorter Than The Shoe Size, The Cleat Will Be Moved By 4 Mm Per Difference In Size. *For Example, If The Shoe Size Is 43 And The Arch Length Measurement Is 44, The Cleat Would Be Moved 4 Mm Forward, Toward The Toe End, From The Center Position Of The Shoe. - If The Measured Arch Length And Shoe Size Are Equal, Set The Cleat At The Standard Cleat Position (See Table Below) Which Is At The Center Of The Ball Of The Foot. - If The Measured Arch Length Is Longer Than The Shoe Size, Move The Cleat Forward, Toward The Toe Side, The Required Length From The Center Position. - If The Measured Arch Length Is Shorter Than The Shoe Size, Move The Cleat Back, Toward The Heel Side, The Required Length From The Center Position.
