My extended family have dermatitis, eczema, psoriasis etc - luckily its usually low level & readily managed & we identify the trigger items quite quickly. Just realised that an increasing problem with a rash on one foot is probably due to an allergy to elastane as the supposedly pure cotton socks that I got are not 100% cotton. This rash is not stylish so I want to get non-allergenic socks quickly so we are all rash-free when summer eventually appears. Have found 100% cotton at People Tree & 100% bamboo at Jasmine Silk but only adult sizes. Can anyone with a similar problem advise on websites or shops for suitable socks for both adults & children
