The more parts a tackle has (rope "legs" between two blocks, determined by the number of sheaves in the blocks), the more the motivating force is multiplied, and the heavier the object

So comfortable!
These work great and very comfortable. I put these on with heel moisturizer cream at bed time. Heels were improved overnight. They are washable too!

Just aren’t large enough.
This is a great idea, and I can wear socks over them and not notice they are there. I just wish they came in a larger size. When I put cream around the edges of my heels where the cracks always are, I cannot stretch the socks wide enough to clear the heel without smearing the cream onto my fingers or on the sock cuff. They do stay in place and aren't squishy at all when walking. They smell good too. The price is right. I wore them overnight and my heels were indeed much softer and smoother than before, and felt moist (tacky) where the cream had been. So they do an amazing job, but after using them six nights, they just aren’t large enough for me to put on without a hassle.

yoga socks
I’m a weirdo and don’t like to walk around barefoot. So, these help me feel like I’ve got socks on while allowing my toes to breathe. I just wear them around the house. They can work as flipflop socks for a quick trip to the mailbox.
I do like to randomly hit the occasional yoga pose so the grippiness is helpful in that regard. I have wide feet and have not found the toe openings to be tight or any other fit problems. So far they have survived standard machine washing.Unfortunately, when I first tried on a pair, the material started to rip. I wear a 7-7.5 shoe size. I think these are made for smaller feet. The material is thin and doesn't stretch. The colors are pretty and it's a good price. I have to return them due to being too small. If you have smaller feet, they are worth trying.

My Favorite Style of Yoga Socks — I Love These
There are so many types of yoga socks out there, but this style is my absolute favorite. These toeless yoga socks are perfect: no individual toe slots, crew‑length coverage, and solid grippies on the bottom. I love them so much. They stay put, they feel great, and they give me the barefoot freedom I want without slipping around on the mat. Total win.
