I purchased this from the Amazon website. The size doesn't fit, so I'm putting it up for sale as part of decluttering. 27.5 cm Solar Green/Core Black Solar Yellow (GW8507) The displayed size is 27.5 cm, but it's quite small, so I think it would be a perfect fit for a 26.5 cm foot. The fabric is thin, so if the size is right, you should be able to get the feeling of playing barefoot.
