Question 1

How do the Recovery Boots work?

Accepted Answer

Each boot wraps the whole leg, from foot to upper thigh. Air chambers inflate and release in an ascending sequence: pressure starts at the foot and climbs toward the thigh, cycle after cycle. On XL and XXL, the chambers overlap to wrap the leg through a full 360°. Six programs offer six different sequences, with pressure adjustable from 30 to 260 mmHg and sessions of 10 to 90 minutes.

Question 2

How do I use them?

Accepted Answer

Plug the hoses into the boots and then into the unit, power it on, step into the boots and close the zip. Set the time, pressure and program, then press start. Lie back: when the countdown ends, the unit switches itself off. Always power the unit down before opening the zip.

Question 3

Are they sold singly or as a pair?

Accepted Answer

The Recovery Boots are sold as a pair: one left leg and one right leg, in the size you select.

Question 4

What colours are available?

Accepted Answer

The Recovery Boots come in matte black, with SAISEI branding on the side panel. No other colourway is offered at this time.

Question 5

How long does the battery last, and how long does it charge?

Accepted Answer

The unit carries a rechargeable 5,200 mAh lithium battery. The manufacturer states 3 to 4 hours of runtime and 2 hours for a full charge on the supplied charger (100–240 V input, 12.6 V / 4 A output). The charger indicator is red while charging and turns green when finished. No outlet is needed during a session.

Question 6

Can I work only part of the leg?

Accepted Answer

Yes. The position key moves the cursor from one chamber to the next along the bar, and the confirm key switches the selected chamber off: it will not inflate during the session. You can disable several — to isolate the calves after a run, for example, or to spare a sensitive area.

Question 7

Are there any contraindications?

Accepted Answer

Yes, and they need reading before you use the machine. The manufacturer advises against use in cases of acute inflammatory skin conditions, arrhythmia, erysipelas, deep thrombophlebitis, pulmonary oedema, acute venous thrombosis, unstable hypertension, or if you wear a pacemaker. This list is not exhaustive: ask your doctor before first use. Never use the machine on broken skin, do not let it get wet, and do not walk around while wearing the boots.

Question 8

Can I take it with me when I travel?

Accepted Answer

Yes. The unit measures 22.5 × 14.5 × 8.5 cm and weighs 1.5 kg, and runs on battery: no outlet is needed during a session. The SAISEI carry bag, included in the box, holds the unit, both boots, the hoses and the charger.

Question 9

Is this a medical device?

Accepted Answer

No. SAISEI builds sports recovery equipment. The Recovery Boots are not a medical device, diagnose nothing, and are no substitute for professional medical advice. If you have any doubt related to your health, speak to your doctor before use.

Question 10

What's in the box?

Accepted Answer

The control unit, both compression boots (left and right leg), two hoses, the 1-to-2 connector, the mains charger, the SAISEI carry bag and the user manual. Everything is ready to use: nothing else to buy.

Question 11

How do I look after the Recovery Boots?

Accepted Answer

Always power the unit down before cleaning. Neither the boots nor the unit are washable: wipe them with a dry or barely damp cloth. Store everything somewhere clean and dry, away from direct sunlight and any heat source. Never pull on the hose to disconnect it — hold the connector.

Question 12

What sizes are available?

Accepted Answer

Three sizes: M, XL and XXL — the European equivalents of S, M and XL. The sleeves measure 77, 86 and 100 cm long and take a thigh circumference of up to 65, 70 and 75 cm respectively. Size is selected in the buy panel before adding to the cart — it is required.

Question 13

How do I choose my size?

Accepted Answer

Measure your thigh at its widest point, standing with the leg relaxed, then the distance from the floor to the crease of your groin. Take the size whose thigh circumference is the next one up from yours: M up to 65 cm (77 cm sleeve), XL up to 70 cm (86 cm), XXL up to 75 cm (100 cm). Too large and pressure disperses; too tight and getting in becomes a chore.

Question 14

I'm between two sizes — what should I do?

Accepted Answer

Take the larger one. The sleeve should close without tension before any air goes in: the machine's pressure does the work, not the tightness of the fabric. If you are hesitating, send us your thigh circumference and leg length and we will settle it with you.

Question 15

Do you have a welcome offer?

Accepted Answer

Yes: 10% off your first order with the code WELCOME10, entered at checkout. The offer is limited to one use per customer.

Question 16

Which payment methods do you accept?

Accepted Answer

Payment is taken on a secure hosted checkout page: no card details pass through our site or are stored by SAISEI.

Question 17

What warranty comes with it?

Accepted Answer

Your Recovery Boots come with a Limited 1-Year Warranty, valid for 12 months from the date of purchase. It covers any quality defect and any damage not caused by the user — control unit, sleeves, hoses and charger included. Should anything fail, write to us with your order number and a photo or short description of the problem, and we will arrange a replacement. Not covered: damage from misuse, accidents, water, unauthorised repair, and normal cosmetic wear. This commercial warranty is in addition to the statutory rights you have as a consumer.

Question 18

How do I contact SAISEI?

Accepted Answer

Through the Contact page. Our team replies within 24 to 48 business hours, Monday to Friday.

Question 19

What does SAISEI mean?

Accepted Answer

SAISEI (再生) is a Japanese word for rebirth and regeneration — a return to an intact state. That is exactly what we are trying to make possible between two sessions.

Question 20

How much is shipping?

Accepted Answer

Shipping is calculated automatically at checkout, from the delivery address you enter. The exact amount appears before you confirm and pay — there is never a surprise afterwards. We ship worldwide.
