Lidl are having a Gluten Free week! The things in their leaflet are a bit limited (and several are GF versions of things that don't normally have it anyway!) but it's a start. I wonder if it is a way of testing the waters, as it were, before maybe introducing some permanent items? That would be nice.
Standard Crocs are a nightmare to size. I buy a size up to accommodate my orthotics, but they are still roomy, which is good for the winter with thick socks. My normal UK size, without orthotics, are too big for me.
