i have the same problem sometimes its an effort for me to walk for long,i cant wear heels etc,unfortunately it doesnt go away because ive had problem for four years and visited various skin dermatologists who say its Eczema.people with dry skin are prone to this.I get relief sometimes from using Vinegar and cotton wool to cleanse the feet then apply sebamed or eucerin creams 10% urea or 20%omega or a hydrocortisone cream maybe containing sulfur or E45 cream.Ive been reading about a cream with great reviews called Terrasil Max obtainable in the USA and im placing an order for next week.
