Customer services will contact you if you click the link right at the bottom of the help and contact page - office hours apply.
However, the buyer cannot expect to keep the shoes if you have made a request for their return, contact them again and politely explain that the legal title for the goods reverted back to you once they received the refund, and that you are now formally requesting the return of your property without undue hindrance or delay. Remind them that ebay is acting as an agent between the two of you and that at no point did ebay hold the title for the goods - whether ebay failed to remind him of his obligation to return the goods is no longer relevant now you have stated that you want your property back.
You will be responsible for the costs of the return and it is important to act fairly and reasonably in order not to compromise your case should you wish to take it further in future.
Citizens Advice Bureau may be able to help you with small claims but start of with ebay support first.
Remember that the small claims will be the court local to you - they may well not bother to contest...
