I bought two types and these have better toe support and are not as shallow. Below the ankle, nice hem and are great for booties and sneakers.

I tried these and the PEDS Ultra Low Microfiber Liner with Gel Tab.  I have no doubt the later will come in handy when I'm wearing ballet style shoes during the summer months.  These are more suited for the booties.  You get the coverage you need without a lot of thick material and they don't slide down or cut off circulation.
