On Maundy Thursdays I occasionally offer foot washing (weird I know, but it’s actually a bit special) so I always revise good foot care beforehand. Once I had a chap who was initially reluctant because he was both embarrassed and afraid, due to suffering with ingrowing toenails. I reminded him that soaking the feet is recommended for that and in the end he enjoyed it so much that he would have rejoined the end of the queue if he could have got away with it! ? Regular soaking is good for the condition, but Boots also do a kit that you might want to have a look at Kate54.
