I use a cane and I need a non-slip floor. what is the best choice besides carpet?

I was thinking about tile but thought it might be too slippery. I think you may have renewed my interest though. Do they make unglazed porcelain tile that has grooved edges? I was leaning towards hardwood with deep beveled edges as it gives my cane something to catch if I were to start to fall.

If you're looking for something a bit softer, you might check-out some of the new fiber floors available as well. Many of these would have enough texture to help with traction but are much softer, warmer, and less expensive than hardwood or tile.
