Didn't notice any sole separation - soles still have plenty of tread - leather uppers still in good shape. Laces look newer so I would guess those have been replaced. The insoles look really good too. The damage I noticed is as follows.
Scuffing on right boot upper moc toe area. Scuff on inside right ankle area inner boot. Various scuffs and dings in leather as would be expected for a preowned work boot of this age. Slight wear to rear heels. Right boot missing "red wing" tag on tongue.
