if i were you, guy, I would contact manfred n-e-r-l-i-n-g-e-r he's a very good guy and he can probably work something out with you to ship the shoes to S.A. (with DHL I presume for africa)
even tho DHL is quite expensive, them shoes are excellent and at only 50 euros for sale
just makes sure you are very accurate in your communication about foot size
see his contacts at
www.n-e-r-l-i-n-g-e-r.comi'm not affiliated with him, but i bought my shoes here and was happy about it
