Footwear Size Chart for Women
At NoStrain, we think that comfort, fashion, and the right fit for each step matter. We design our women's sandals and women's slippers with love, engineering them to provide support for your feet all day, no matter if you are at home or on the move. For your convenience, please see our detailed footwear size chart for women.
Our size chart features U.S., U.K. and European sizes as well as foot length in centimeters, so it's simple to choose the correct size regardless of where you're located. NoStrain women's slippers and sandals are true size, but in case you're a half size or have larger feet, we suggest going up a size for the most comfortable fit.
To measure your foot, simply stand with your heel against a wall and mark the tip of your longest toe. Measure the length. Refer to our chart to find your size based on the measurement.
To find the right fit is to have greater support and maximum comfort—tying back to NoStrain's promise. Confidence comes from knowing your women's sandals and slippers will fit perfectly. For inquiries, our customer service team is always available. Step into comfort with NoStrain.
One wrong size. That's all it takes to ruin a perfectly good pair of slippers.
You find the style you like, you place the order, it arrives — and either your toes are hanging off the front or the slipper is so loose it slaps the floor every step you take. It's not the slipper's fault. It almost never is. Wrong sizing online is the reason most footwear returns happen in India, and it's entirely avoidable.
This page exists to make sure that doesn't happen to you.
Why Rubber Slippers Need Extra Sizing Attention
Most footwear materials — leather, fabric, jute — soften and adjust to your foot over time. Rubber does not. What you get on day one is what you wear on day one hundred. There's no break-in period, no give, no gradual adjustment.
That's actually a good thing once you're in the right size. The moulded footbed holds its shape, the support stays consistent, and the slipper remains as comfortable in month three as it was the first time you wore it. But it does mean you need to get the sizing right before you order, not after.
There's one more thing worth knowing. Feet tend to swell by up to half a size through a normal day — more so in Indian summers. A slipper that fits snugly at 9 AM can feel uncomfortably tight by 2 PM. This is why, if you're ever between two sizes, always go with the larger one. Every single time.
How to Measure Your Foot at Home — The Right Way
Take a plain white sheet of paper. Place it flat on a hard floor — not on carpet, it shifts. Stand on it barefoot with your heel touching the wall behind you. Have someone mark the tip of your longest toe with a pencil. If you're alone, lean forward carefully and mark it yourself.
Now measure from the wall's edge to that pencil mark in centimetres. That number is your foot length, and it is far more reliable than whatever size you remember buying two years ago.
Do this for both feet. Most women have one foot slightly longer than the other — this is completely normal. Order for the longer foot, always.

NoStrain slippers are true to size for standard-width feet. Women with wider feet or a fuller instep should size up by one — the extra length creates the lateral room you need without the slipper becoming loose overall.
Which size should I order if my foot measurement falls between two sizes?
Always choose the larger size. NoStrain rubber slippers have a firm contoured footbed that holds shape without stretching. A slightly roomier fit stays comfortable all day. A slightly tight fit becomes a problem within a few hours — especially in warm weather when feet naturally expand.
Who Should Consider Sizing Up
Not every foot is standard width, and that's fine. Here's a quick guide:
If you have wide feet: Go one size up from your measured length. The additional size gives your forefoot the space it needs. The heel may feel slightly less snug initially, but it settles in.
If you're pregnant or experience regular foot swelling: Size up without hesitation. Feet during pregnancy retain fluid and can increase by a full size, sometimes permanently.
If you're buying for everyday indoor wear across long hours: A marginally larger size will always feel better than a precise fit after six or seven hours on your feet.
Frequently Asked Questions - Footwear Size Chart
Q: What is Indian Size 6 in EU and US sizing for women's slippers? Indian Size 6 equals UK Size 4, US Size 6, EU Size 37, and a foot length of approximately 23.5 cm. This is the most commonly ordered size for Indian women and fits a medium-length foot. If your measurement is exactly 23.5 cm, this size is your match.
Q: Do NoStrain rubber slippers run true to Indian size? Yes — NoStrain follows standard Indian sizing conventions aligned with UK measurements. If you normally wear Indian Size 6 from other Indian footwear brands, order the same size here. The fit is consistent and does not run small or large for standard-width feet.
Q: My left and right foot are different sizes. Which one should I measure? Always measure both feet and order for the longer or wider foot. Wearing a slipper that's slightly large on one foot is far more comfortable than wearing one that pinches the other. This applies to all footwear, not just slippers.
Q: Can I exchange if the size doesn't fit? Yes. NoStrain offers hassle-free exchanges for size issues. Check the Return & Exchange Policy for full details on the process and timelines.
Q: Are rubber slippers suitable for women with flat feet or arch problems? NoStrain's arch slippers and angular slippers are specifically designed with contoured footbeds that support the natural arch of the foot. They are not medical-grade orthotics, but many women with mild flat feet or arch fatigue find them significantly more comfortable than standard flat chappals for daily wear.
