these blister packs are quite literally a god-send when travelling and on holiday. especially when you buy new shoes or sandals for holiday and the heat takes its toll. they stay on and don't budge until the heal is healed up or until you remove and they really prevent any further damage to the area. cannot rate highly enough and i don't go anywhere or on any long hikes without them in my bag.
During my Gold Duke of Edinburgh I got some nasty blisters which were really painful. The moment I put one of these plasters on I couldn't feel my blisters at all and then, they didn't bother me for the rest of the expedition. I would recommend these to anyone.
