My feet are really REALLY large. And fortunately there are a lot of [DIY sandals](http://abeautifulmess.com/2015/07/make-your-own-espadrille-sandals.html) out there. Some even sell them, made to be easy to modify. [Sseko Sandals](https://ssekodesigns.com/ribbon-sandals) are the most well-known. Unfortunately they don't come in my size. Another option is to have someone on Etsy make me some extra-large sandals.
