Shoe help

Options
Ive been a new balance wearer since I started running, tonight I bought Adidas.. . They were cheap, felt great and will replace my long overdue indoor treadmill shoes.

Only upon reading more about them they are trail shoes? Not disclosed in the store. What are trail shoes? Will they still be good for treadmill or better outdoor? I have my current outdoor NB with only about 150 miles on them that I could move to indoor?
