As a subtle twist on block colour socks, the ‘shadow rib’, when done well, is pretty much unequalled - as with these Pantherella Santos Shadow Rib Cotton Lisle Socks, which are realised using special knitting process that, as the name suggests, enables them to have a two-colour ‘shadow’ effect within the rib pattern. In this case, the shadow holds the brighter of the colours, muting the tones to great effect. These 200-needle fine gauge knit socks are made in Pantherella’s historic Leicester factory from an Egyptian cotton rich blend, and to a classic gentleman’s half calf length, finished by pressure-free hand linked toes for smooth seams. The design includes contrast plain toes, heels and welts.
