2TOMS BLISTER SHIELD

Not the most glamorous item you’ll ever purchase, perhaps, but a great deal more enticing than the alternative. Chafing and blisters are the scourge of the distance runner and this is the best preventative product on the market. It performs amazingly well, doesn’t rub off or lose effectiveness with the sweat of long miles, leaves no residual stains and is not made from animal fats, as is the case with some similar products. £14, preventsportpain.com
