These are the best slip-on sneaker option on the market. They are sturdy, comfortable, and most importantly for me, non-slip. Sketchers has another popular no-tie sneaker option, the Skechers Sport Women's Gratis-In Motion Fashion Sneaker, and although it's lighter, it had virtually no grip on the bottom and I slid around on flat surfaces even when just walking normally. I work in a hospital, so that was obviously a deal-breaker. I found the Rock Around to be the better-quality alternative. They're so light and slim, so I don't get the bulky feel I usually have with sneakers.

I'm usually between a 5.5 and 6, but the 5.5 was out of stock so I went with the 6 and it fits just fine with socks.
