yes that is what we suggest at work, you can buy boot stretchers in Timpsons for about 10 quid, or just use a leather softener on them, but you have to remember that leather loosens naturally with wear anyway and if they do not stretch to fit you with wear but u artificially stretch them they will end up in wrinkles around your ankles.
Thanks for your advice, I will put leather softener on and then wear them around the house, see if that works. Dont know why I've got 1 calf bigger than the other.
