Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned.
These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

These socks are wonderful!
I was wanting toeless socks to wear at night when I sleep. I put moisturizer on my feet before I go to sleep and wanted socks to hold in the moisturizer. But, I cannot stand having a sock that covers my whole foot. So, I thought, gee, I wonder if they make socks that do not have toes? Well, I found some that have a gel pad, got those, and hated them. They felt awful and I couldn't sleep with them on. Finally, though, I came across these socks -- no gel pad, no toes. They are wonderful. They have enough hold to stay on my feet all night, but are very comfortable. In fact, when I get them on my feet, I forget they are even there. They are soft and well-made and have really cute colors/patterns. I understand that they are probably for exercise/yoga/pilates classes, but I find them perfect for my needs. I love them!

GENIUS IDEA !❤
I'm a nurse and on my feet for 10 hours a day. I wear nursing clogs but really don't like to wear socks. I feel like they smother my feet. These allowed me to wear socks but have my toes free and it feels wonderful!
