"true, dat, road shoes can be harder to walk in. But you probably don't do a round of free weights before or after your spin class, road shoes will be fine for in and out of the locker room, just be careful on the slippery tile. " From Trek420

But I do a round of free weights before or after at least 50% of the spin classes I attend. So it really depends on what you want to do and what you want to carry. If you get road shoes without cleats you might slip and fall on hard floors. If you get cleats on your road shoes you will be required to wear other shoes and change into your cycling shoes at class time. That's why I recommend mountain biking shoes.
