With CV controllable centre frequency, resonance Q and notch offset along side FM, strike and a complex dual input with wave shaping limiter, the I 47 is truly a filter

I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

Enables the person to move around while wearing.

These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.

Not worth the time or money

Never buy these, they causes feet cramps and bad pain even if you use foot pain cream

Does the job but dangerous to walk with!

Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!
