I struggle with blisters, and have been trying loads of different shoes/socks, fed up on my 4th pair of trainers in as many months now, back to the cheap neutral ones from the adidas outlet shop at cheshire oaks.
The support in one pair ruined my feet, even with vaseline/body glide and compeed
The stitching on others also gave me blisters
I have soft feet and still got blisters, so toughened the skin up, still got them. used several pairs of twin skin socks
Changed to another pair of trainers which drops the heel and now ive got achilles tendonitis..
Ive not had much luck in finding a pair of non blistering supportive shoes..
What i have found is popping a blister and letting it dry out heals it quicker
A hydrocolloid plaster, like compeed's do also help healing but the blister will still be there/itll still be wet underneath
A friend has informed me of some cushioning sold at boots you can stick directly onto your foot, which she swears by and wears for any run.. Sometimes you just cant win.
Hope you find a soloution which works for you. My quest continues.
