Flip flops might give the impression of being the ultimate care-free footwear, but if you get a blister in between your toes because of these holiday staples, you'll definitely know about it.Schlepping to the beach and back every day in the Summer can leave you with some serious sores, so we asked experts from The College of Podiatry, Matthew Fitzpatrick and Michael O'Neill, for their advice. 'Flip flops are the number one choice for Summer footwear, but their lack of structure means they can cause heel or arch pain, as well as those between-toe blisters, or 'thong blisters' as the Aussies call them' explains Matthew. 'This is where the retainer between the big and second toe causes a sore area and eventually a blister'. While both podiatrists suggest opting for a more structured sandal or one that doesn't have a toe post insteaed, if you do prefer flip flops, they have the following advice: - Avoid getting the flip flops wet or walking long distances in them, as you're more likely to develop irritation.- Experiment with fabric flip flops rather than plastic ones – some people find these cause less pain between the toes. Accessorize has a large range.- Buy some silicone toe post protectors, available from large pharmacists, as these can protect you from some of the friction.- If you do develop a blister, stop wearing the flip flops and wash the blisters before applying an antiseptic. Walking around bacteria-laden pavements with an exposed blister is a bad idea, as you can pick up an infection.
