Cute and Comfortable
I have now purchased at least three packs of these Freetoes, so that says something; I love to wear flip flops and sandals but while walking some distance they can chafe and cause foot issues so I use the socks as a buffer, they are attractive and comfortable, especially in warmer months, and have solved the chafing issue. Highly recommend!

GOOD IDEA, BAD RESULTS
As u walk it slides up to your ankle since there's nothing to secure it between the toes, ends up looking like you have a ankle bracelet. Fabric is NOT soft and comfy. Ended up giving them all away to the my cousin that was traveling with me, she had forgotten her socks so she was desperate for anything. She had the same problem as I but because she is obese so the socks fit snug on her so took a bit longer to hike up to her ankle. Im medium built.. I purchased 2 sets so it was a waste of my hard earned money.

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.
