Permanent Marker On RubberI have a pair of new shoes with rubber non-skid soles. Bought them onsale, price on bottom of sole in permanent black marker. Have tried alcohol, both rubbing and denatured, Dawn, little pad soaked in oxy-clean, fingernail polish remover, etc. Problem is, I sit with my leg crossed lots of time when wearing casual clothes and shoes such as this, don't want the price "glaring". LOL.
