A testing and indexing apparatus and method for shoes is disclosed. A block is inserted into the interior of the shoe and clamps the heel portion of the sole fixed flat in relation to a plate. This plate is moved on rails until the ball or widest part of the shoe is set between laterally disposed clamps. The clamps are tightened on the ball of the shoe and the plate is fixed in position on the rails. Both the lateral clamping mechanism and the heel block clamp mechanism are attached to a generally rectangular base, however they are separate and the lateral clamping mechanism is axially rotatable along the axis of the clamped shoe and is attached to a torque wrench type device. Thus the shoe may be twisted axially to a pre-desired point and a reading taken to index the flexibility of the shoe in this dimension. This testing mechanism replicates the type of stress put on the shoe when worn walking or running during the midstance subphase when the entire body's weight is being transferred across the planar surface of the foot. People having foot pain from incorrect strides or faulty pronation in the midstance subphase of gait (at the point when the heel is striking the ground) require a shoe with less flexibility than others. Additionally, the device may be used to both index various brands of shoes in this manner and to determine when an old shoe needs to be replaced.
