not necessarily - sometimes increasing surface area is better in terms of higher probability of being in contact with a 'rough' spot. sometimes a smaller surface area is better for increasing interlocking and increasing required shear to break this interlocking. |

How many times have you discovered that if you don't weigh the foot enough, it'll slip off? |
