Solovair Derby Boots UK7/US men's 8. Goodyear welted sole construction (meaning you can get them re-soled) made in England with a full leather upper. The “original” Doc Marten boot, before Doc Marten split from the Solovair company and began making cheaper boots outside of England. To me, these are more comfortable than Doc's because they have a shank, which makes them feel more stable. Just a generally higher quality of build and materials.
