I think Baker makes about the best insole shoulder on the planet. If it was missed in the photo essay the hides are in the tanning liquors for a year. Only one other tannery in the world, AFAIK, comes even close. And no one else gets anywhere near the quality.
It's expensive and time consuming to bring into the US, what with the VAT and shipping and customs brokerage fees, etc.. But every so often several of us form an ad hoc buyer's consortium and bring in a roll or two of shoulders, bends and welting. I think I still have most of two double shoulders and two whole bends left.
