Trying to get into MTB

Ugh. It will all depend on what your foot fits.
The "standard" that everyone goes by is the 5-10 line, Impacts and Karvers. Those are too wide for me, , even the women's.
Teva Links
Adidas
and there are some others, Vans etc.
Mainly you want a stiff, sticky sole.
I just purchased some Teva Links, in a kids 6.5 because I have a narrow small foot. Zappos and Shoebuy.com will be your friend if no one carries these kinds of shoes locally.
