I have a white pair that I've had for 2/3 years, as comfy as slippers, love them.
So last year I bought a pair of gold ones, and a pair of black ones, exactly the same size, style etc (38 Madrids)
Both the gold ones and the black ones are soooo uncomfortable and feel completely different from the white ones.
How can this be? I don't want to spend any more money on any more in case they are uncomfortable again, but I just want them to be like my comfy white ones?? Waaaa.
