1. Will this really work on my feet? I've tried powders, sprays, antibacterial soaps, activated charcoal... nothing lasts.

That's normal, because most of those products mask the odour, not the cause. Sudoblok is not an odour masker or an antibacterial. It's an antiperspirant: it reduces sweat at the source, and without moisture the bacteria that cause odour have nothing to thrive on. We treat the cause, not the symptom. Most clients notice the difference from the very first application, and the effect lasts 24 to 48 hours even in boots or sneakers worn all day long.

2. Isn't putting aluminum on your feet every day dangerous?

No, and this is an important nuance to understand. The concerns circulating about aluminum in antiperspirants revolve around two very specific things: old studies from the 1960s–90s on breast cancer and Alzheimer's (never reproduced or confirmed since), and more recently, aerosol formats that Health Canada monitors due to inhalation risks.
Sudoblok is not an aerosol — it's a cream applied directly to the skin. So there's zero inhalation risk. Skin absorption is estimated at less than 0.01% by scientific committees, and on the feet it's even more negligible since the skin there is thicker. The Canadian Cancer Society, Quebec's Chief Scientist, and the FDA all confirm: there is no demonstrated link between topical aluminum-based antiperspirants and cancer or Alzheimer's.

3. Will it clog my pores, dry out my skin, or make a fungal infection worse?

Sudoblok does not clog pores. It forms a temporary plug at the opening of sweat ducts that disappears with the next wash. The formula contains glycerin, so it moisturizes instead of drying out the skin, and is free of fragrance and dyes that could cause irritation. If you have an active fungal infection, treat it first with an antifungal. Once the skin has healed, Sudoblok becomes your best ally in preventing a recurrence: fungal infections thrive on moisture, so we cut off the moisture.

4. When exactly do I apply it and how many times a day?

Apply once in the morning on clean, dry feet before putting on your socks. Focus between the toes and on the soles—that's where sweat builds up the most. The effect lasts 24 to 48 hours, so no need to reapply midday. For heavy-duty days (hockey, hiking, 12-hour shifts in work boots, tropical vacations), also apply the night before at bedtime—it doubles the effect. The 120 ml format lasts between 4 and 6 months with daily use on feet only.

5. At the gym, at yoga, or when I take off my shoes at someone's house, I feel embarrassed. Will I really be able to stop worrying about it?

You're not alone. About 15% of adults deal with plantar hyperhidrosis to some degree, and the vast majority end up avoiding social situations because of it: turning down an invitation to come inside, showing up early at the gym to change before anyone else, keeping your shoes on when visiting. Sudoblok is designed to solve this exact problem. No heavy fragrance that gives away you just applied something, no powder that leaves residue on your socks. You apply it in the morning, put on your shoes, and stop thinking about it for the rest of the day. The real difference isn't just in your feet—it's in your head: getting back the freedom to move without overthinking every step.

Traditional stick or spray antiperspirants are formulated for underarms, period. Sudoblok is designed first and foremost for feet — where moisture builds up, where it festers, where odor starts.

Classic antiperspirant

Designed in Quebec, for feet that have been through it all.

Stick and spray antiperspirants were designed for underarms. Feet needed something different: a lightweight texture that dries fast, goes on in two seconds in the morning, and lets you forget about it for the rest of the day.

Your routine in 3 steps.

Two minutes in the morning, dry feet all day long.

01 — Dry

Title

After showering, dry between the toes

Wash and dry your feet thoroughly, paying extra attention between the toes. Sudoblok is applied to perfectly dry skin, with no residual moisture — this is the key to optimal results.

02 — Apply

Title

A few drops for both feet

Pour a few drops into the palm of your hand and massage onto the sole, top of the foot, and between the toes. The texture dries in under a minute, with no greasy film or residue.

03 — Put On

Title

Socks, shoes, forget about it.

Once Sudoblok is absorbed, put on your socks and shoes as usual. A single morning application covers the entire day. For extended activities (running, skiing, long days on your feet), reapply before starting.

Dry feet, real stories.

Marie-Hélène

I'm no longer embarrassed to take off my shoes.

Before Sudoblok, I always kept my shoes on at friends' houses. Now, I can take them off without thinking twice. My feet stay dry all day and my sneakers smell way less.

A real difference by the end of your shift.

I'm a nurse, twelve hours on my feet per shift. My feet were always clammy, my socks soaked. Since I started applying Sudoblok in the morning, my feet stay dry until the end of the day.

My husband keeps stealing my bottle.

We tried it on my winter boots (my feet were freezing because of the moisture). My husband tested it on his hockey skates, and he's been telling his whole team about it. We now have two bottles at home.

How to use Sudoblok on your feet.

Three simple steps for dry feet from morning to night.

Step 1

✅

Apply a few drops to clean, completely dry feet, ideally in the morning after showering. Cover the sole, top, and between the toes.

❌

Do not apply on irritated skin, open blisters, fungal infections, or immediately after leg hair removal.

Step 2

✅

Gently massage until absorbed. Sudoblok dries in under a minute with no greasy residue. Wait until fully absorbed before putting on socks.

❌

Avoid using too much: a few drops are enough for both feet. More is not better.

Step 3

✅

One application in the morning covers the entire day. For very active days (running, hockey, long walks, skiing), reapply just before the activity.

❌

No need to apply morning and night: let your skin breathe at night so it stays balanced.

FAQs

1. What exactly is Sudoblok?

Sudoblok is a versatile antiperspirant made in Quebec, designed to temporarily reduce perspiration on multiple areas of the body. Unlike a deodorant that simply masks odour, Sudoblok targets the cause directly: it reduces sweat output thanks to its active ingredient (Aluminum Chlorohydrate), preventing the bacteria responsible for odour from proliferating.

2. What areas of the body can I apply it to?

Sudoblok is formulated to be versatile. You can use it on the scalp (for hair that gets oily fast), feet (sweating and odours in shoes), hands (sweaty palms), underarms, the face (as a makeup base to last all day), or any area where perspiration bothers you. A small amount is enough to cover a large surface.

3. Is it really different from a regular deodorant?

Yes, absolutely. A deodorant masks and neutralizes odors, but you keep sweating normally. Sudoblok is an antiperspirant: it forms a temporary plug at the opening of the sweat ducts and reduces the amount of sweat produced for 24 to 48 hours. It uses the same mechanism as clinical-strength antiperspirants sold in pharmacies, but it's formulated to be applied anywhere on the body, not just under the arms.

4. Is the aluminum in it safe?

Yes. Aluminum Chlorohydrate has been approved by Health Canada and the FDA for over 40 years as an over-the-counter antiperspirant active ingredient. The rumors linking it to breast cancer or Alzheimer's stem from older studies that have never been reproduced or confirmed since. The Canadian Cancer Society and Quebec's Chief Scientist have publicly stated their position: no proven link. Absorption through the skin is less than 0.01%—far less than what you ingest daily through water and food. Also good to know: Health Canada's recent concerns apply only to aerosol formats (inhalation risk), not to creams like Sudoblok.

5. How quickly will I see results?

Most clients see a difference from the very first application. The full effect develops over 3 to 5 days of daily use, as the plug stabilizes. If after a week you don't see any change, reach out to us — we offer a 60-day satisfaction guarantee (see question 10).

6. Will it stain my clothes or leave residue in my hair?

No, as long as you use the right amount. The formula is dye-free and designed not to leave white residue on dark clothing or weigh hair down. The classic mistake is using too much: a small dab is enough for the entire scalp, one pump on each foot, and a small amount under each arm. At a normal dose, you can get dressed or style your hair right after.

7. Is it suitable for sensitive skin, during pregnancy or breastfeeding?

The formula contains no fragrance or dye, which significantly reduces the risk of irritation. For very reactive skin, do a patch test on a small area (inside of the arm) before the first full application. Regarding pregnancy and breastfeeding, topical aluminum is considered safe by health authorities due to its very low absorption, but as a precaution, we always recommend speaking with your doctor or midwife before starting any new product.

9. How long does a bottle last and where is it made?

Sudoblok is 100% made in Quebec. The 120 ml format lasts an average of 2 to 3 months with daily use on the scalp, and between 4 and 6 months if you only use it on a targeted area like your feet or hands. Store at room temperature, away from direct light and extreme heat.

10. What if Sudoblok doesn't work for me?

You have 60 days to try it. If you're not satisfied for any reason, we'll give you a full refund, even if the bottle has been opened. No questionnaires, no justification needed, no product to ship back. Just email us at [insert email address] and we'll take care of everything.
