Hi,
I'm actually asking on behalf of my mum, she's got a problem with the arches in her feet so has bought some (very expensive) sandals to help support them. They help with the pain, but the stitching along the back of ankle strap is really rough and rubs her in a big way.
Does anyone know if there is anything she can paint/rub on the stitches as a coating of some sort?
Thanks very much.
