All shoes, particular if you aim to keep the cost down have a certain resemblance with each other. It cost additional monies to have a new pattern and grade it for all the sizes required. Look at EG's own shoes and the one's made for RLPL. The difference between the two are only small design variations, which do not affect the basic pattern.
Andrew Lock's
Gryffin might be based on the same pattern as Herring's
Rushden, but the Gryffin has an additional line of perforation, along the top-line and down the throat. Gryffin comes on last 208, while the Rushden comes on last 205 (I'm not
au fait with Cheaney's lasts as to have an opinion which one is preferable).
Last but not least Lock's shoes clocks in financially considerable lower (GBP 250) compared with the Herrings at GBP 325, At this stage, Andrew Lock deserves encouragement,as the product he offers looks thoroughly professional.
