What masah is

Masah means wiping over your socks during wudu instead of taking them off and washing your feet. It’s permitted on footwear that meets certain conditions, and scholars have written about those conditions for a very long time.

In everyday terms, it means you can make wudu at your desk, at the mosque, or at a service station, without finding somewhere to wash your feet and without going back to your prayer in wet socks.

We make socks. We’re not scholars, and nothing on this page is a ruling. We’ll tell you what the socks are and what the conditions are, so you can decide — or ask someone qualified.

The conditions

What the socks have to do

HydroSox wudu design sheet: structured construction that holds its shape and stands upright when not worn, durable waterproof materials, and long-term durability.
A pair of black HydroSox standing upright unworn, holding their shape.

Scholars set conditions for the footwear you’re allowed to wipe over. Three of them are about the sock itself, and those are the three we can speak to.

  1. Water mustn’t get through to your foot

    Cotton socks soak through. Ours have a Porelle® waterproof layer sealed inside them, so water doesn’t reach the skin. It’s the same layer in every pair we make — there’s no separate wudu version.

  2. They have to hold their shape

    They need to sit over the foot as a covering rather than collapse flat against it. Ours stand up on their own when you take them off, and there’s a photograph of that below.

  3. They have to stay on your foot

    Shaped so they stay in place through a normal day rather than working loose and sliding down.

There’s one more condition, and it’s about you rather than the socks. You put them on after a full wudu, with your feet washed. From your next wudu onwards, you wipe.

Examined by

Who has looked at them

The differentiator is the named membrane. Everything else in this category tends to be asserted rather than evidenced.

We didn’t want to make a religious claim about our own socks, so we asked people qualified to look at them.

  • Shaykh Mufti Saiful Islam

    Founder and Principal of the JKN Institute in Bradford, where he also heads the fatwa service.

  • Mufti Amjad Mohammed

    Founder and Principal of Dār al-ʿUlūm al-Zaytuniyya in Bradford, and a lecturer in Islamic jurisprudence. He has written extensively on Islamic law for Muslims living in Britain.

There’s no certificate, because no organisation issues certificates for socks. What we have is two qualified scholars who examined them. If you follow a different school or a different scholar, ask them. We’d rather you were sure than take our word for it.

Every day

Why people buy them

Hajj comes round once. Most people buy these for the other fifty-one weeks of the year.

  • Wudu at work

    Washing your feet in a basin built for hands is awkward, cold and slow — and then you sit in damp socks for the rest of the afternoon.

  • Ten minutes back, several times a day

    Not usually the reason people buy the first pair. Often the reason they come back for a second.

  • Everywhere that isn’t a mosque

    Airports, building sites, university prayer rooms, car parks in February. Wudu rarely happens somewhere designed for it.

Travelling

Hajj, Umrah and travel

  • Long days, shared facilities

    Pilgrimage means long days, busy washrooms and nowhere to dry anything properly. A pair that keeps water out and dries overnight is worth the space in the bag.

  • Take more than one pair

    Most people travelling take two or three. They wash cool and air dry, which is slower than a tumble dryer, so one pair won’t keep up.

Order

Choose your colour and size

Praying five times a day means washing them often. Most people here keep three pairs so there’s always a dry one, which is why three is already selected.

Size guide

Measure the foot rather than relying on shoe size — sizing is not consistent across brands, and the foot length is what actually has to fit.

Size Foot length UK shoe
S 22.0 - 24.0 cm UK 3-5
M 24.5 - 26.5 cm UK 6-8
L 27.0 - 29.0 cm UK 9-11
XL 29.5 - 32.0 cm UK 12-14

How to measure

Stand on a sheet of paper with your heel to a wall, mark the tip of your longest toe, and measure heel to mark.

Between two sizes

Between two bands? Take the larger one. These are a close, stretchy fit — a size down grips the toes and shortens the life of the membrane.

What are wudu socks?

Waterproof socks made so you can wipe over them during wudu instead of washing your feet. They need to keep water out, hold their shape and stay on the foot — those are the conditions scholars set for the footwear itself.

Are these certified for wudu?

No, and no sock is — there’s no organisation that issues certificates for this. What we have is two UK scholars who examined the socks.

Do I still have to wash my feet?

You wash them as part of a full wudu before the socks go on. From your next wudu onwards, you wipe over them instead. The masah page sets it out step by step.

How long can I keep wiping for?

Scholars give twenty-four hours if you’re at home and seventy-two if you’re travelling. The clock starts at your first wipe after wudu breaks, not when you put the socks on. That’s the part most people have slightly wrong.

What’s different about these and your other socks?

Nothing in the waterproof layer — it’s the same in every pair. What matters for masah is that the sock holds its shape rather than collapsing onto the foot, and that’s built into how it’s knitted.

Are these the same as leather socks or khuffs?

Not the same material. Khuffs are the leather footwear the classical rulings were written about. These are a modern waterproof version aimed at the same three properties. Whether that counts as equivalent is a question for scholars, and the masah page explains how it’s discussed.

Can women wear them?

Yes. They’re unisex and start at UK 3. Go by your foot length rather than the men’s or women’s size you’re used to.

Will washing them ruin them?

Cool wash, inside out, no fabric softener, then air dry away from the radiator. Heat and softener are what finish off a waterproof layer, not wearing them.

Ask us

Ask us anything about how they’re made

If you need a specific detail to make up your own mind, or your imam does, ask us. We’ll tell you what’s in them and how they behave. We won’t tell you whether your wudu is valid, because that isn’t ours to say.
