I use saphir renovator every few months and brush em like crazy. During that time I may (or may not) also put just a lick of wax...a really small amount. Cordo is already impregnated with oils and too much wax dulls them.
It is very interesting as how quickly their marketing has spread. Even The Shoe Mart carries them (albeit a limited selection). They do provide a nice niche among the US, UK, and Italian makers, at least in the US. Lots of great makers from Budapest (i.e., Vass) too so it appears the Spaniards are getting more styles to compete.
I think they have presented more styles this year than the number of goals Messi scored the last calendar year.
Glad to see Carmina has become more accessible - they make an exceptional shoe. As long as they maintain quality and a wide selection, at a relatively attractive price, than I'll be a customer for life.
