Men's tango shoe suppliers and brands
NeoTango
Neotango do a good range of men's tango shoes. They do good plain styles, and some which are funky but still kinda 'formal'. They also do men's dance sneakers and tango practice shoes. They have a website, and do do mail order, but they have a very limited range on the website compared to the shop. NeoTango offer leather, suede (cromo) or half-suede (half-cromo) soles. Update: there is now also a non-flash website for European customers, with prices in Euros.
Tango Brujo
The new kid in town, Tango Brujo shoes have already got a devoted following. They have a reputation for being super comfortable, and are popular with a lot of nuevo dancers. Tango Brujo itself is a Buenos Aires based dance school (an excellent one, I highly recommend it), but has a shoe and clothes store on the ground floor. The owners of the school wear Tango Brujo shoes, which is a good sign. It has a website which has finally started selling shoes. There are also some US and European suppliers, and there will be more as they become better known. They do both conventional mens tango shoes and practice shoes and dance sneakers.
Darcos Tango Shoes
Another fairly big name. They have a big shop in Buenos Aires which sells music as well as tango dancewear and tango shoes, and other dance shoes. They claim to be 'magic shoes', and are more generous with their padding in the soles than most other tango shoe brands. They do men's tango shoes in a good range of styles, from conservative to flashy 40s, and they do dance sneakers and practice shoes in a range of really crazy styles.
Susana Artesanal
Susana sells handmade tango shoes. She offers a wide range of handmade men's tango shoes in classic styles, and you can order through her website.
2x4 al Pie
2x4 have a unique selling point - they have interchangeable soles, so you can swap between suede, leather and rubber soles. They're best known for their men's tango shoes, and several of the really big names wear them. They have a distinctive modern-40s look.
