I've bought Nike, I've bought New Balance... New Balance always feel tight and make my feet sweat... in 100+ degree weather summers, if your feet aren't getting air, you're going to have a problem. Nike always rubs and gives me blisters, and generally don't provide nearly as much cushion and support as Puma. Also, Nike always felt like they were 'pressing' down and out when I ran, instead of up and down, straight.

Puma are far more comfortable, airy, light with the right movement (no out! Why would you go out?!), and are the only shoe I ever buy anymore for use... Why waste my hard earned money on a shoe less than serviceable when I can buy cute, functional, GREAT shoes that fit right (true to size, and the measuring/sizing chart they provide is accurate if you're uncertain), last forever (I still have my first pair I bought 9 years ago... they still fit, feel great. Look a little used, but still fantastic!). In 9 years... I've only had to buy 3 pairs (and still keep and use my old ones!). That alone should tell you what kind of quality you get when you buy Puma.

They ARE expensive in stores, but on Amazon you get some pretty good deals, I suggest shopping for them here. Know your size, but buy here.
