ISO 3379,17235 Footwear Lastometer
Footwear Lastometer  is used to determine distension and strength of leather grain. It is applicable to boot and shoe upper leather and light leather. It uses the clamping ring and cap to clamp round specimen and a steel ball to press against the centre of the flesh side of the specimen. The pressure and distension produced are recorded at grain crack and at burst (if bursting occurs).Â
