WHY NOTHING HAS WORKED
You were handed the right idea in the wrong hardware
Insoles. Supportive shoes. Stretching. Ice. Maybe a cortisone shot. Maybe custom orthotics that cost $450. Every one of them works on your foot while you are standing on it. All of them clock out when you do.
But the worst moment of your day is the first step out of bed. Here is why.
While you sleep, your foot relaxes and points down, like a ballerina pointing her toe. The band under your arch goes slack and short. Your body patches the tiny tears in it overnight, but it patches them in that short position. Then you stand up. The band gets yanked to full length in a split second, and the fresh patch rips open. That stabbing first step is the sound of last night's repair being torn.
Doctors know all this. It is exactly why they hand out night splints, the big plastic boots. The idea is right. The boot is the problem. It is hard, it presses on your toes, it catches on the covers, and if you sleep on your side it keeps you awake. Almost everyone quits it within weeks. Not 1 person quits because it did not work. They quit because they could not sleep in it.
So no, you were not doing it wrong. Nothing you bought was built for the 8 hours that decide how your morning feels.
NO TRADEMARKED TECHNOLOGY. NO MIRACLE. 8 QUIET HOURS.
What it does while you sleep
The knit holds your arch up and limits how far your foot can point down while you sleep. That is the whole trick. It is the same idea as the splint podiatrists prescribe for morning heel pain, moved into something soft enough to actually sleep in.
How you use it
What is inside the knit
2 sleeves in every pack. 1 for each foot.
Solava vs the splint in your cupboard
The splint idea is right. This is about which 1 you will still be wearing in week 3.

WHO TO BELIEVE
The idea is your podiatrist's. We changed the hardware.
Keeping the foot from pointing down overnight is not our invention. It is standard, boring, textbook care for morning heel pain. That is exactly why we trust it. The plastic boot was just impossible to live with, so we put the same job into a knit.
What it does. And what it does not.
A claim you can check beats a promise you have to trust.
STILL DECIDING
Fair questions
Will this fix my plantar fasciitis?
Will this fix my plantar fasciitis?
No, and be careful with anything that says it will. Most feet improve over months with simple care. Solava's job is the 8 hours of sleep nobody else covers, and comfort you can feel while you get there. You have 60 nights to decide if it earns its keep.
What if it feels too tight?
What if it feels too tight?
It should feel snug and even, never tight. It is 15 to 20 mmHg, the light end of real compression. If you feel tingling or your toes get cold, take it off and go 1 size up. The exchange is free.
Can I wear it during the day too?
Can I wear it during the day too?
Yes. It is thin enough for normal socks and work shoes. That is the point of the 2 pair system. 1 pair works your shift, 1 pair works your night.
Do I wear it with or without socks?
Do I wear it with or without socks?
Either. On bare feet at night, or under a normal sock by day. The open toe keeps your toes free both ways.
How do I wash it?
How do I wash it?
Cold wash, air dry. Heat is what kills compression knits, so keep it away from the dryer. With 2 pairs you can wash 1 and wear 1.
When will my order arrive?
When will my order arrive?
The delivery window with real dates is shown above the add to cart button, and every order carries tracking from day 1. If tracking ever looks stuck, message us through the store and a person will chase it.
What if it does not help me?
What if it does not help me?
Send it back within 60 nights of delivery for a refund. Worn is fine. We cannot ask you to judge a night sleeve you never slept in.
Will it lose its stretch?
Will it lose its stretch?
Any knit loses some snap after months of nightly wear. Cold washing and air drying slow that down a lot, and rotating 2 pairs roughly doubles the life of both.
TONIGHT
Your foot will repair itself again tonight
Either that repair holds past your first step, or it tears open again at 6am. The same trade happens every single night, whether you buy anything or not.
The 24 Hour System is 2 pairs for $79. Less than the leading sleeve's list price for 1. You save $19, and you cover your shift and your sleep. Wear them for 60 nights. If your mornings are not different, send them back and we refund you.
Summer is peak flare season. Start tonight.
