Simple stripes, colors and patterns are all that is visible when you are wearing shoes, but kick them off and you can show off famous figures from classic paintings. They may not be fit for formal wear situations, but are certainly fun for everyday occasions (and a great idea for sock puppet shows).

These series of silly socks from ChattyFeet is equally informal about their titling of the various pairs. Famous artists are given name twists, resulting in Andy Sock-Hole and David Sock-Knee. Other pairs include Frida Callus and Feetasso (from Frida Kahlo and Pablo Picasso).

From the designers: “The master of modern art David Sock-Knee is on hand (or foot) when you want to impress with your knowledge of home-grown British artists. They are just the thing to wear to that exhibition opening event and don’t forget to snap a ‘sockie’ photo when you visit famous galleries. Follow in this famous face’s footsteps by recreating your favourite holiday scenes in acrylic – just don’t splash any on your socks!”

ChattyFeet is a quirky brand that offers “silly sock personalities” for adults and children alike. The studio’s line of cheeky characters colorfully drawn onto comfortable cotton socks.

In theater, the ‘fourth wall’ refers to the imaginary barrier between performers and their audience – the work of this illustrator evokes a kind of ‘fifth wall’, treating the sky above as invisible canvass for drawing upon.

Featured previously, French artist Thomas Lamadieu is back with new sets (SkyDesign and SkyFace) as well as fresh work in his SkyArt series from around the world, with illustrated shots taken and drawn from South Asia and Europe to the United States.

His recognizable style is pushed in new directions as he explores difference spaces and ways of filling them in, including some cartoons that breach the sky barrier and start interacting with infrastructure and spatial elements beyond the central area of focus.

In SkyFace, his portraits seem to push out from their frames, filling up their allotted space and then some, pulling back buildings to be revealed. In SkyDesign, his creations begin building out their own aerial infrastructure, crafting fanciful structures in the sky and manipulating the sun, moon, stars and other celestial elements seemingly at their fingertips.
