This week I tried the same model of boots on dd in 2 different Clarks shops.
One told me the correctly fitting size for her was 10F - which was strange because that's what she measured last winter - but they were adamant that 10 1/2F was too big.
The other shop fitted her at 11F.
How can their staff be properly trained if they can differ by 1 whole size in their fittings? And should I take this up with Clarks?
