An other name for the "rope shoes" = espadrilles
in google: espadrilles how to make
http://en.wikipedia.org/wiki/Espadrilleshttp://www.maunesabaters.com/page7a.html => when you click on the photo's you can see some detail of the soles.
It could be an interesting test to try and make them.
The more skills one has, the better.
I'd like see a report with photo's on the forum (if you can)
However you can buy them in Belgium for 0.50 EUR to 2.00 EUR for a basic standard pair.
(unless it's a very fancy pair you want => then the sky is the limit).
I don't know if you can find them locally.
One word of warning: they don't like wet conditions.
