How Long Does It Take to Get Used to New Insoles?

You've slipped your new insoles into your shoes, taken a few steps, and something feels… different. There's a firm bump under your arch, your heel sits a little deeper, and by the end of the afternoon your feet are talking to you. Is that normal? Did you buy the wrong pair?

Almost certainly not. Your feet have spent years walking one way, and you've just changed the ground they stand on. Here's what to expect, day by day, and how to tell the difference between "getting used to it" and "something's not right".

The short answer

Most people get used to new arch insoles in about 1 to 2 weeks. NHS orthotics advice is to start with around an hour on the first day, add an hour or so each day, and most people can wear them all day within 7 to 10 days. Firmer support can take up to 2 to 3 weeks. Mild aching is normal; blisters, sharp pain or numbness are not.

Why there's a break-in period at all

Good arch insoles do more than cushion. They change how your foot lands and where the pressure goes, by lifting the arch and cupping the heel. That's the point, but it also means:

  • Your muscles work a little differently. The muscles in your feet and lower legs adjust to the new position, which can leave them mildly tired at first.
  • Your skin meets new pressure points. Areas that never took much load before, such as under the arch, now do.
  • Your brain notices. The feeling of something under your arch is unfamiliar, so it stands out until it becomes normal.

NHS orthotics teams describe some aching in the feet or legs as normal while you get used to insoles, and the same thing happens with ready-made foot arch support insoles, just usually more quickly.

Your break-in diary

Your break-in diary: firm and noticeable on day 1, mild aches on days 2 to 4, feeling natural by the end of week 1 and barely noticeable from week 2

Day 1: "Hmm, I can feel these." The insoles feel firm and very noticeable, especially the arch. That's expected. Wear them for about an hour, ideally around the house or on a short walk, then switch back to your usual insoles.

Days 2 to 4: "My arches are a bit achy." A mild, tired ache in your arches, calves or knees is the most common thing people notice. It should fade once you take the insoles out. Keep building up slowly.

End of week 1: "Oh, these are quite comfy." For most people the insoles start to feel natural, and you can wear them for most of the day. One NHS leaflet notes that most people can wear them all day within 7 to 10 days.

Week 2 onwards: "I forgot they were there." You barely notice them, and you can start using them for longer walks, shifts and exercise. If your insoles have firm support or your old shoes were very flat, it can take a little longer: some NHS services say mild aching may last up to 2 to 3 weeks.

A simple wearing-in schedule

This follows the pattern most NHS orthotics departments recommend. If you've worn insoles before, you may move faster.

Day How long to wear them Tip
1 About 1 hour Around the house or a short walk
2 About 2 hours Take them out if your feet ache before the time is up
3 About 3 hours Keep activity light to moderate
4 to 7 Add an hour or so a day Stay at a comfortable time for a day if needed
8 to 14 Most of the day, then all day Now try longer walks or a full shift
After 2 weeks All day, including exercise Build up sport gradually, starting with a warm-up

The golden rule from NHS leaflets: if your insoles cause discomfort before the time is up, take them out for the rest of that day, then go back to the time that felt comfortable the next day.

Normal or not? A quick traffic-light check

What you feel What it means
Normal A firm feeling under your arch; mild, tired ache in your arches, calves or knees that fades when you take the insoles out Your feet are adjusting. Keep building up slowly
Slow down Aching that starts early in the day or lingers into the evening Go back to a shorter time that felt comfortable, then build up more gradually
Stop and get advice Blisters, rubbing or red marks that don't fade; sharp or stabbing pain; numbness or tingling; pain that keeps getting worse Something isn't right with the fit or the type of insole. Stop wearing them and check the troubleshooter below
New insoles, normal or not: a firm feeling and mild ache are normal, lingering aches mean slow down, and blisters, sharp pain or numbness mean stop and get advice

NHS leaflets advise stopping and getting advice if pain or discomfort persists for more than a few days, even when you're building up gradually.

Troubleshooter: if this, try that

If you notice... It may be because... Try this
Your arches ache Your foot muscles are adjusting to the support Shorter wear for a few days, and a gentle arch and calf stretch in the evening
Your toes feel squashed The insole is too long or too thick, or the original insole is still in Take out the shoe's original insole and trim the toe end to match it
Your heel slips The shoe is loose, or the insole is too short Check the size, and tighten your laces so your heel sits in the heel cup
Rubbing or blisters Too much too soon, or the edge is catching Stop for a few days, check the trim line is smooth, and restart more slowly
The arch feels like a hard lump The arch support sits in the wrong place for your foot, or it's too high for you Check the heel is pushed right to the back of the shoe; if it still digs in, a different arch height may suit you better
Your knees or hips ache Your walking pattern is adjusting Go back to shorter periods; if it continues beyond 2 weeks, get advice

In one trial of navy recruits given new contoured insoles for training, the most common problems were blisters and arch pain, each reported by fewer than 1 in 10 people, which is why going slowly at first matters.

Choosing arch insoles that are easy to get used to

The right pair makes the break-in period shorter and more comfortable. When you're comparing foot arch support insoles, look for:

  • Contoured but not rigid arch support. Firm enough to hold your arch, with some give, so it doesn't feel like a hard bump.
  • A deep heel cup, so your heel sits in the right place and the arch support lines up with your arch.
  • Cushioning on top, to soften the new pressure points while you adjust.
  • A trim-to-fit, full-length shape, so the insole fits your shoe without bunching or squashing your toes.
Insoles and the running chain: a runner's leg with the knee highlighted, ZakSole insoles in trainers showing arch support and heel cushioning, and a progress log with days 11 to 15 ticked

Our foot arch support insoles are designed this way, and they work as arch inserts for shoes you wear every day, from trainers to work boots. If you mainly want arch insoles for shoes you wear casually, our casual range is slimmer. Check the size guide before you order.

ZakSole insoles come with a 30-day trial, which gives you time to follow the full wearing-in schedule before deciding. Not sure which type suits your feet? Read how to choose the right insoles for your foot type.

When to stop and get advice

Stop wearing your insoles and speak to a pharmacist, GP or podiatrist if:

  • you get blisters, broken skin or red marks that don't fade
  • you have sharp pain, or pain that gets worse rather than better
  • you notice numbness or tingling in your feet
  • your insoles still hurt after 2 to 3 weeks of building up slowly

If you have diabetes or reduced feeling in your feet, NHS advice is to check your skin daily while getting used to new insoles, because you may not feel a problem developing. Ask your GP or podiatrist before using new insoles.

FAQs

How long does it take to get used to new insoles?

Most people get used to new insoles in about 1 to 2 weeks. Start with around an hour on the first day and add an hour or so each day. NHS orthotics advice says most people can wear them all day within 7 to 10 days, though firmer support can take up to 2 to 3 weeks.

Is it normal for new insoles to hurt?

Mild aching in your arches, calves or knees is normal for the first few days and should fade when you take the insoles out. Sharp pain, blisters, numbness or pain that keeps getting worse are not normal, and are a sign to stop and get advice.

Should I wear new insoles all day straight away?

Wearing new insoles all day from the start isn't a good idea, as it often leads to aching or rubbing. Build up gradually instead: about an hour on day one, two hours on day two, and so on until they feel comfortable all day.

Why do my arches hurt with new arch insoles?

Arch insoles change how your foot takes your weight, so the muscles and tissue under your arch work differently at first. A mild ache usually settles within a week. If the arch feels like a hard lump or the pain is sharp, the support may be the wrong height or position for your foot.

Can I run in new insoles straight away?

Running in new insoles is best left until you can wear them comfortably all day, usually after about 2 weeks. Then build up gradually: use them for a warm-up or a short, easy run first, and increase the distance over the following runs.

What if my insoles still hurt after 2 weeks?

If your insoles still hurt after 2 weeks, check the fit first: take out the original insole, trim the toe end to the right length and make sure your heel sits in the heel cup. If they still hurt after 2 to 3 weeks of gradual wear, the type of insole may not suit your feet, so get advice from a podiatrist.
