I haven’t run for over 15 years after being a competitive runner in my teens. Had a big fear of blisters and discomfort …on the return to chasing past glories. I saw Sums advertised and thought I would give them a go. Going straight into 5,8,10km runs after so long away and my feet have been absolutely fine!! (My times maybe not so much 👀). I would definitely recommend for both comfort and looks. Great purchase
