Inexpensive, light weight, comfortable, flexible and good quality.
I have Nike Zoom and get this one for spare, Nike has similar type of
flixible runing shoes like this but it costs $100 and up.
  I took a chance buying this one for half price of Nike and I love them.
Flexibility is what I like most, I am runing on paved road and they work fine.
For trail runners, you will need different type of shoes,
