Unreasonable!!

I bought a pair of shoes for my husband as a birthday gift on 3 September and gifted them to him yesterday on his birthday 18 October. If you compare the size 9 sent to me to any other size 9 shoe it is far larger! Superbalist refuses to exchange them as it is after the 30 day period. The shoes are still available on there website so I see no reason why they cannot make the exchange. I am most disappointed with the service and I will be taking it further!
