Feel a softshell. Its smooth, like a frog. The spiny has a little roughness to it.
Softshells like a round-grained, clean, nonabrasive sand. They can get infections from abrasions. A bare bottom tank for a softshell is very stressful.
The only thing that can hurt their feet is a very rough, ragged gravel/sand. Big round grains are fine. Bare bottoms are just so... blah. Its just another thing youd be taking away from them along with its freedom. Give it as best an envionrment as you can. Turtles are tough, its hard to hurt them.
