These slippers are comfortable and lightweight. I bought them to replace a pair from another company that had mildewed. I was worried they might not be as non-slip as my old ones, but I felt very secure in the shower with them. I specifically shopped for a pair with no drainage holes, because that is where mildew grew in the other pair. If you travel a lot, these weigh nothing, so they are perfect for tossing in a suitcase.
