The Goodyear welted method
All of our footwear manufactured here at NPS Shoes is proudly all handmade; part of this process is the Goodyear welted method.
The introduction of the ‘Goodyear welting machine’ by Charles Goodyear in 1872 was to revolutionise the production of footwear. Goodyear welted footwear acquires its name from the long strip of material called a ‘welt’ which is sewn to the upper and insole of the shoe or boot by means of chain stitch. The (out)sole is then attached separately to the welt by means of a lock stitch. There are up to 200 highly skilled stages in the making of a pair of ‘Goodyear welted’ shoes and this traditional method of manufacturing serves to provide the following key advantages in terms of:
- Exceptional comfort: The cavity created by the inseam between the inner and outer sole is filled with a flexible compound that moulds to the shape of the wearer’s feet.
- Strength: Comfort combined with durability to provide strength, outstanding performance and excellent shape retention.
- Insulation: The flexible compound that is sandwiched between the inner and outer soles provides excellent thermal insulation and protection from uneven surfaces.
- Easy to Repair: As long as the uppers are taken care of, it is easy to re-sole worn welted footwear by sewing or heat-sealing new soles to the existing welts, to give a life expectancy up to 20 years.
- Flexibility: The ‘Goodyear’ welted construction is adaptable to almost every style of footwear which enables NPS to respond and meet new trends in fashion.
