Cold, aimed at the spot that hurts.
Localized cryotherapy for sore knees and ankles, plantar fasciitis, tired skin, and stubborn fat. Pain treatments take five minutes — text us to book a time, get sprayed, walk out. Facials and body sculpting are booked with us directly.
Pain somewhere else? We also treat the back, sciatica, legs, shoulders, and more. Email mark@floatboston.com for more info.
A precise stream of cold, not a cold room.
We use pressurized CO₂ to put controlled cold, down to −110°F, on one specific area for a short, measured time. You stay dressed, you stay standing or seated, and only the spot being treated gets cold.
The cold drops the surface temperature fast. Blood vessels tighten, which calms swelling, then reopen and bring fresh, oxygenated blood back to the area. It does what an ice pack is trying to do, in a fraction of the time and much deeper. No drugs, no needles, no downtime.
- Joint pain and swellingKnees, ankles, elbows, wrists, and plantar fasciitis — after a game, a run, or a long week.
- RecoveryBefore or after training, between games, alongside whatever else you already do.
- SkinPuffiness, dull tone, and fine lines on the face, neck, and chest.
- Stubborn fatThe pinchable layer under the skin, as part of a program you commit to.
Joint pain relief
Five minutes of targeted cold on a knee, two smaller joints like ankles, elbows, or wrists, or plantar fasciitis. Most people feel the difference before they leave.
Cryo facial
Six steps: cryotherapy, lymphatic massage, collagen fog, red light, and an antioxidant finish. Firmer, brighter skin and less puffiness, with no redness afterward.
Body sculpting
Cold that breaks down fat cells and tightens skin, as part of a program you commit to.
Knees, ankles, and heels are what we do most.
Nine out of ten pain treatments we do are joints, and most of those are knees and ankles. So that's what we've built this around: one fast, flat-priced treatment for the joints that take the most punishment, plus plantar fasciitis, the heel and arch pain that makes the first steps of the morning hurt.
Precise, penetrating cold lowers the temperature of the joint in seconds and signals the body to slow inflammation. Most people feel less pressure, stiffness, and ache within seconds. As the area warms back up, blood vessels reopen and flood the joint with fresh, oxygenated blood, which supports tissue repair and clears out inflammatory byproducts.
The whole visit is about five minutes. You can do it as often as you need, before or after a workout, and alongside almost any other recovery method.
Athletes in season
Runners, hockey and soccer players, lifters, weekend-league regulars. Get a swollen knee or a rolled ankle calmed down between games instead of waiting it out on the couch. NCAA, NFL, and MMA athletes use targeted cryotherapy for the same reason.
Before you train
A joint that's stiff and cranky going into a workout moves better once the swelling is down. Five minutes on the way to the gym, the rink, or the start line.
Joints that never quite settle
Old injuries, overuse, arthritis flare-ups, tendinitis, plantar fasciitis. Cold gets to the problem itself, without medication and without downtime, and you can come back as often as it helps.
What it does for pain
Less pain, fast
Cold slows the nerve signals that carry pain. Most people feel relief within seconds, and it can last for hours.
Less swelling
Blood vessels tighten, which calms inflammation and takes pressure off the joint or heel.
Better movement
With the swelling down, stiff joints and tight heels move more freely, so you can walk, train, or play.
Faster recovery
As the area rewarms, fresh blood rushes back in to support repair. No drugs, no needles, no downtime.
One price for a joint. A better one for two.

Open the cryo mapAnti-Anxiety Cryotherapy Treatment
A quick, gentle cold fog before you get in the tank, like a cold plunge-lite. It gives your nervous system the reset a cold plunge does, without the shock of jumping into ice water. You walk into your float calmer, quieter, and ready to let go.
Great for first-time floaters, busy minds, and anyone who has trouble settling in during the first part of a float.
Book it on our booking page for the 10 minutes right before your float.
Nervous System Reset
Ten minutes of targeted cold on the neck and chest that switches you out of fight-or-flight. Most people walk out calm and clear-headed. The full version of the anti-anxiety treatment, on its own or before a float.
Firmer, brighter skin without a needle.
Controlled cold air over the face, neck, and chest briefly tightens the skin and blood vessels, then floods the area with fresh, oxygen-rich blood as your skin warms back up. Tone, color, and glow improve right away.
The cold also stimulates collagen, the protein that keeps skin firm and elastic. Over the days and weeks after each session, clients notice tighter skin, less puffiness, and softer fine lines. Every facial runs through the same six steps, from the first pass of cold to a red light mask and an antioxidant finish.
No redness, peeling, or irritation afterward, so it works before a wedding, a shoot, or a regular Thursday. A single session lasts a few weeks. A series of weekly sessions builds on itself and lasts longer.
Six steps, start to finish.
Cryotherapy
Controlled cold passes over the face, neck, and chest. Blood vessels tighten, then flood the skin with fresh, oxygen-rich blood as it warms back up, so tone and glow improve right away.
Under-eye cryo lymphatic massage
A chilled massager works gently under the eyes to move trapped fluid out, easing puffiness and that tired, heavy look.
Cryo lymphatic massage
The same cold massage along the cheeks, jaw, and neck moves fluid toward your lymph nodes, for a less puffy, more defined face.
Collagen fog
A fine cryo fog across the face that stimulates collagen, the protein that keeps skin firm and elastic. This is where the lasting change starts.
Red light mask
An LED mask with red and near-infrared wavelengths that calms redness, supports repair, and builds on the collagen response from the fog.
Antioxidant finish
We finish with Hylunia Ultimate Antioxidant Cream, made with peptides and plant stem cells, to hydrate and lock it all in.

Body Sculpting
Fat cells are more sensitive to controlled cold than skin, muscle, or nerve tissue. Put the right temperature on the right area for the right amount of time and the fat cells break down, a process called cold-induced apoptosis. Your body clears them through the lymphatic system over the following weeks.
Here's the part most places won't tell you. The cold is a tool, not a miracle. It speeds up fat loss you're already driving. It does not replace it. Buy sessions, change nothing else, and you'll see modest results at best.
If you're not ready to do your part, this isn't the right program for you, and I'll tell you that on the free consult rather than take your money.
Sold in 4-packs, because everyone's different.
Most people need somewhere between 8 and 20 sessions to get where they want to be, and nobody can tell you on day one where in that range you'll land. So we sell body sculpting four sessions at a time. You see how your body responds, then decide whether to keep going.
How often
It's a weekly appointment. We check in as you go, and if you get the result you wanted sooner than you expected, you stop.
Who it won't work for
Cryo works on subcutaneous fat, the pinchable layer between skin and muscle. It does nothing for visceral fat, the kind packed around your organs. If you're not sure which you're carrying, get a DEXA scan before you spend anything here and bring me the results. I'll tell you straight whether this is worth your money.
What happens in a session
Four steps, 45 to 60 minutes depending on the area: core and obliques, full legs, arms, or thighs and hips.
Deep freeze spray
Our strongest spray reaches deep into the fat. We work in sections, 30 seconds at a time. Cold at first, then little to no discomfort.
Collagen fog
A finer cold fog that builds collagen and tightens the skin as we go, so the skin keeps up with the fat loss.
Lymphatic massager
A cold massager pushes the broken-down fat toward your lymphatic system. Most people say it feels like very cold butter.
Power Plate
Vibration helps flush what the massage couldn't. Then you're done and back out into your day.
This isn't magic.
You see the ads all over the place. Weight loss without the hard work! Just one shot, or one pill and you'll be skinny. That's not how life works. If you're not working out, eating right, or taking care of your body, it won't work and it's not worth it.
I tested this on myself before I offered it to anyone. Six weekly sessions, eating right and staying active.
Six months later, with only walking for exercise, it has held. The cold sped it up. The habits are what kept it.
Four sessions at a time.
Everyone needs a different number of sessions, generally 8 to 20, so you buy four, see how you respond, and keep going if it's working. Every 4-pack comes with a float.
One 45 to 60 minute session: deep freeze spray, collagen fog, lymphatic massager, and Power Plate.
