Compeed is now owned by Johnson and Johnson, the Bandaid people. In Australia it's sold as Bandaid Blister Block, and is available from chemists and supermarkets. Scholl also make a blister product, but it's for use once a blister has formed, whereas Compeed is really useful to prevent blisters. Apply it as soon as you feel a hot spot on the foot.
I could be wrong, but think there is only one size available here. In Spanish phamacies on the Camino, you will see a whole stand of Compeed in different shapes and sizes.
