Thanks to the many Californians who've told me that Mexican Folklorico shoes are a good - and economical - substitute for flamenco shoes, for those on a budget.
Although I've never examined a pair of Mexican dance shoes, I can understand why they would stand up well to the rigours of flamenco.
I remember some years ago, a native of Mexico joined our flamenco school and I was amazed how quickly he mastered the steps - until he gave us a short demonstration of Mexican dance, and I realized he was already accustomed to stamping his feet at high speed!
