Would these be suitable to wear in the shower, ?. i have ms and always afraid of standing in the shower, i have a non slip mat, i slipped a bit on it.

Does size 10.30/11 child does that mean men's size....

What do the each of the sizes refer to? Is it men's/women's?

I have quite narrow feet.. Would these be tight enough?
