I used to used blisters from the discounter, until I came by chance to the SOS blister Elastoplast. I must say that the durability and adhesive power is a lot better, the pavement even survive a day in the pool easily. Blisters heal under the pavement well and can not be ignited. The patches provide immediate pain relief. Another advantage is that the paving of Elastoplast are virtually invisible, so that my feet plays with bubble in sandals a good figure. One can also paving preventive use but is already an expensive 1 per piece. The price is also the only downside for me and is a star deduction.
