Well from my own experience I can tell you that shox running shoes have more cushioning and shock absorbers than others. Please visit www.scienceofrunning.com for specifications.
New Balance shoes once enjoyed widespread recognition because, unlike other brands that only had factories in places like Vietnam, Indonesia, and China, they owned factories in both the UK and the US. British-made shoes were considered the highest-end, boasting the best workmanship and quality, with US-made shoes coming in second place, and both workmanship and quality far surpassing those produced by contract manufacturers in other countries.
Asics makes a variety of running shoes to fit a variety of different age groups. Academy sports offers Asics running shoes for kids. They have a great selection and fair pricing.
The manufacturer may be able to provide you with detailed information about the Salomon running shoes. Local running stores can also tell you details about the Salmon running shoes and how they compare to the other shoes.
Asics makes the best running shoes for women right now. New Balance also make great running shoes for women as well. Both brands should be looked at.
To the best of my knowledge the advantage of the Asics Gel running shoe is that it has gel in the insoles for more comfort and support. These shoes are available at Kohl's, Zappos, Amazon and Ebay.
The discus shoe is different from regular shoes because discus shoes are used in a sports event (throwing the discus obviously). However, regular shoes are used for walking, running, sprinting, etc.
Nike Air Max shoes differ from other shoes in a multitude of different ways. One such way is the increased flexibility and versatility that one has when wearing these shoes.
What makes the Terra Plana running shoes so different is the fact that they practically weigh nothing and bend every which way the foot bends naturally. Its almost like running barefoot.
asics by far
Paul Green footwear makes mostly dress or buisness casual shoes that would not be appropriate for running or athletic wear. You will need to find a different brand of shoe.
Forefoot shoes are different to your typical running shoes due to the fact they are made using the lightest material to insure minimal shoe weight, and also not as much material on the shoe as a typical running shoe may have. This insures that you have maximum control over your shoes and they feel completely natural to you and so that they are not dragging you down. However, just because they are lighter, does not mean they are far superior to other shoes, they may help your performance a bit but i would not say the difference is very noticeable.
If you have decided to start training for a marathon I would say nike makes the best men's running shoes for running marathons. They are the most sturdy and wont fall apart.
