I'm so impressed by RoToTo's engineering, they are the masters of sock fabrication, yarns, gauges, rare specialist machinery, experience crafts people .. not to mention their hip unisex designs.
this tie-dye pattern was actually stitched into the sock not dyed
the inside sole is cushioned and brushed to make it fluffy
what's more all the yarns of this sock are treated with an organic deodoriser
they are 70% cotton and come in 3 sizes .. £20 plus shipping, made in Japan
