Ouch, that could be painful, and possibly in breach of health and safety regulations. But if LOCOG management insist that all none sponsored shoes or trainers are removed due to corporate deals, then I am afraid they may well suffer the wrath of these regulations, which, if I'm not mistaken, hold management 'solely' responsible and personally liable for any injuries caused - sorry couldn't resist
Have LOCOG carried out a full risk assessment for athletes walking around in bare feet in order to conform with lucrative sponsorship deals?
Will LOCOG risk damaging expensive athletic feet in their quest for loads of money, or will they get cold feet?
