The strength of adhesion of sole of a shoe to its upper is determined by measuring the force needed to pull off the sole from the upper. A suitable last is placed inside the shoe which is then placed on a straight edge acting as a fulcrum for applying load on the joint of the sole and upper. The maximum load the sole is able to withstand before coming off is determined and reported as the sole adhesion strength. This test can be carried out either at the heel or at the toe of the shoe. 

Sole Adhesion Tester consists of a load cell and digital indicator to indicate the load applied at the junction of the sole and the upper, a lever arrangement to transmit the load exerted on the toe piece to the spring dynamometer, a straight edge fulcrum for resting the shoe on during the test, and a set of interchangeable toe pieces having different curvature. 

The load indicator indicate the load applied on the joint directly in kilograms, taking into account the mechanical advantage of the lever transmitting the force from the toe piece to it. The indicator has the facility of peak hold and tare. 

There is an screw arrangement to hold the shoe with last and have the arrangement to up and down movement (load application to the shoe) with the help of the motor, gear box, and screw arrangement.

The toe piece are five in number and having different curvature to enable toes and heels of different shapes and sizes to be tested. The length of arc of each toe piece, however, is the same to ensure that the load is applied only on a fixed length of joint. They are made from carbon steel for giving a long operational life. Any one of the toe pieces can be held in the equipment at one time.

The fulcrum on which the shoe is placed during the test has adjustable height to enable soles of different thickness to be tested. The height of the fulcrum is adjusted with the help of spacer strips provided with the instrument.

The instrument is finished in painting and bright chrome plating to give it a corrosion resistant finish.
