We are told often that flexibility is a positive thing, flexible joints, flexible mindsets, flexible timetables, these are all good things. The Superfeet FLEX range is another option to be… Flexible. For a start, they come in 3 thicknesses, FLEXthin 3mm, FLEX 4mm and FLEXmax 5mm but it doesn’t stop there. These insoles offer flexibility all the way through from heel to toe and they will hug and support your feet all day long. A great way to introduce insoles if you haven’t worn them before and a wonderful way to be kind to your feet.
