How to Break In New Flats Without Blisters

Few things ruin a new pair of shoes faster than a blister on day one. Flats are lower and lighter than heels, but they still need a short settling-in period, because the edge of the shoe sits right against the skin of your heel and toes. Here is how to ease into a new pair without paying for it later.

First, make sure the size is right

Breaking in can soften a shoe a little, but it cannot fix a pair that is truly the wrong size. Before you start, check that your toes are not pressed against the front and that your heel is not sliding out of the back. If you are unsure, measure your foot and compare it to the size chart. Our guide on finding your flat shoe size walks through it step by step.

Start at home, in short sessions

Wear the new pair indoors for an hour or two at a time. Walk around, climb stairs and sit down in them. This shows you exactly where the shoe presses, and it costs you nothing if the pair needs to go back. Wear them with the socks you plan to use, so you test the real fit.

After each session, take them off and check your feet. Red patches are an early warning. If a spot is already sore, stop for the day and let the skin recover before the next try.

Build up gradually

• Days 1 to 3: wear them around the house for one to two hours.
• Days 4 to 6: take short outings, such as a coffee run or a quick errand.
• Week two: wear them for a half day, and carry a spare pair if you will be out longer.

Rotate your shoes. Giving a new pair a day off between wears lets the shoe relax and your skin rest.

Protect the usual trouble spots

Flats typically rub in three places: the back of the heel, the little toe and the top of the big toe joint. Tackle them before they hurt.

• Apply a small strip of blister tape or moleskin to the back of the heel before wearing.
• Rub a thin layer of balm or anti-chafe stick on areas that tend to rub.
• Wear thin no-show socks. They cut friction on shoes with a low cut and are barely visible.
• Keep your feet dry. Damp skin blisters faster, so skip heavy creams right before you go out.

Gentle ways to loosen a tight spot

If one area is firm, bend the shoe gently with your hands for a minute, flexing the sole and pressing the sides of the upper. Wearing thick socks around the house for short spells can also help stretch a snug spot slightly. Go slowly and do not force it; aggressive stretching can damage the shape of the shoe.

Avoid shortcuts that sound clever but are risky, like soaking shoes or using high heat. They can warp the shoe and may void any chance of a return.

If a blister does appear

Stop wearing the shoes. Wash the area gently, leave an intact blister alone if you can, and cover it with a proper blister plaster. Give it a few days before trying the pair again. If the same spot blisters repeatedly, the issue is probably fit rather than break-in time.

When to stop breaking in and exchange

Some discomfort in the first few wears is normal. Constant pinching, numbness or a heel that keeps popping out is not. If a pair is still painful after a couple of weeks of gentle wear, it is likely not your size or shape. For many shapes, Mary Jane flats with an adjustable strap are easier to fit around the foot, which can help if you struggle with slip-on styles.

Try them at home

Order with confidence: shipping is a flat $3.99 worldwide and free when you buy 2 pairs or more, and you have 30 days to exchange or return if the fit is not right. Pick your size from the chart and start your break-in gently.

Frequently asked questions

How long does it take to break in flats?

Most people feel a pair settle in within one to two weeks of short, regular wear. It varies with the shoe shape and your feet.

Should I wear socks to break in flats?

Thin no-show socks can reduce rubbing while you are breaking a pair in. Wear them at home first so you know how the shoe feels with them.

Can I return flats I have tried on at home?

Wearing them indoors on a clean surface is the safest way to test the fit. Check the return terms and keep the shoes in good condition while you decide.
