Asics Piranha SP running shoes are a very good product and have many key features. You can find out their weight on the following website http://www.amazon.com/ASICS-Men's-Piranha-SP-Running/dp/B0029NZDC6
The Asics Nimbus for men is a good choice for a lightweight shoe. This shoe is designed for runners and has a lightweight design that isn't too bulky. The Asics Nimbus have gel insoles for comfort that don't weigh down this sneaker.
There is no model shoe created by Asics called Asics trainer. But Asics does have a trainer line called the Asics Gel trainer which is a cross trainer shoe.
The following website offers reviews and comparisions with Asics running shoes: http://www.runningshoesguru.com/ This website also offers much more information about Asics and other running shoes.
Asics are not really sold very much anymore. I would look toward a different running shoe such as Nike or Reebok. The poor quality and customer service from Asics should send you away.
