We noticed this because it was really one of the Kayhoma designers' goals for these hospital socks. Kayhoma hospital socks are thick overall, and they can replace warm cotton socks to help those who wish to sleep in socks. This has a special meaning for hospital socks. Whether in the hospital or in the delivery room, putting on or taking off socks is not as simple as usual, and having a pair of socks that provide both grip and warmth is the dream of many people, and such a desire is not widely known.
We set this goal for Kayhoma hospital socks: These socks should be very soft and loose, super stretchy, breathable and comfortable. First of all, they should be high-quality cotton socks with good thermal properties. Kayhoma hospital socks have achieved this goal.
They should also be compatible with different sizes of feet, even with swelling, as pregnant women and the elderly often experience edema from poor circulation in their legs. So the band at the top of Kayhoma hospital socks is 2 inches wide, they are very elastic, very loose, they can't switch blood circulation, they just keep the socks comfortably above the ankle.
The top grip design of Kayhoma hospital socks is very thoughtful. These anti-slip strips cover 95% of the sole of the foot, and they also take into account the lateral grip. What's especially important is that these anti-slip gels don't put any pressure on your feet, you won't feel them at all, and they're as comfortable as regular thick cotton socks.
This is why Kayhoma is the best hospital socks brand.
