Instead of spending hours browsing shop windows, examining thousands of models from the comfort of your home while sipping your coffee is much more convenient. In this respect, online shoe shopping is a real luxury, but before pressing the “Buy” button, the same question crosses almost everyone’s mind:
“Will they fit my feet?”
Because of this question, buying shoes online can sometimes feel like leaving it to chance. But online shopping is not a game of chance. If you measure your feet correctly and read the fit and size details properly, the shoes you buy online will fit perfectly, as if you had tried them on in a store.
At Derimarket, we send hundreds of orders from our Pegia and Cool Moon collections to every corner of Türkiye and the world every day. The thing we see most often in this process is this: Not the wrong size, but choosing the wrong fit is what causes returns. That is why, in this guide, we have gathered everything in one place, from choosing your size and measuring at home to model-specific tips and a hassle-free return process.
Section 1: Size and Fit (the Shoe’s Internal Volume) Are Not the Same Thing
The most common misconception: “I’m a size 38.”
In fact, you are not “a fixed size.” The shoe’s length is one thing, while the volume/fit it provides around your foot is another.
- Size: The shoe’s length.
- Fit: The shoe’s width, toe shape, ball-of-foot volume, ankle opening, and interior depth.
The same size can feel completely different in two different models. A size 38 high heel and a size 38 winter boot will not fit the same foot in the same way.
Let’s quickly go over fit terminology:
- Narrow fit: The ball-of-foot area may be tighter, and the toe box narrower.
- Regular fit: Standard measurement; most people choose their usual size.
- Wide fit: More spacious inside; it creates a feeling of “roominess,” especially in boots worn with thick socks.
Section 2: Scientific Foot Measurement at Home: Clear Results with Paper and Pencil
You do not have to guess your shoe size just because you do not have the metal measuring device used in stores at home. If done correctly, the paper-and-pencil measurement method described below is highly reliable.
Time to measure: Evening
Feet swell as you walk during the day. For most people, morning measurements come out “small.”
Step-by-step measurement
- Place a blank A4 sheet of paper on the floor, with its short edge against the wall.
- Wear your socks according to the shoes you will buy:
- Winter boots → thicker socks
- Ballet Flat/loafer → thinner socks
- Step on the paper, with your heel lightly touching the wall.
- Mark the tip of your longest toe (hold the pencil vertically).
- Measure the distance from the wall line to the mark (e.g., 24.5 cm).
- Measure both feet. Most people have one foot that is larger. Always use the measurement of the larger foot as your reference.
Width tip
Measuring the widest part of your foot (between the big toe joint and the little toe joint) with a tape measure can be a lifesaver when choosing between a narrow and wide fit. If you have wide feet, lace-up models or boots with a roomier fit will be more suitable.
Section 3: Model-Specific Size Selection Tips
There is no “one rule” for online shopping; it depends on the nature of the model.
1) Sneakers / athletic shoes
The foot slides forward while walking. A little space at the toe feels more comfortable. Many people find a half size larger sneaker more comfortable (this may vary by brand).
2) Classic high heels
With high heels, the foot is pushed forward. If the toe box is narrow, the ball of the foot may feel cramped. For wide feet, especially in models with narrower toe boxes, size selection requires extra care.
3) Boots and tall boots
- Leather boots: They are mostly made to a true-to-size fit.
- Sheepskin-lined boots: They may feel firmer the first time you wear them; the lining adapts to the shape of your foot over time. Buying a size that is too large can create a feeling of “looseness” later on. The inner volume of the fur-lined Pegia and Cool Moon boot models is made to a true-to-size fit. Therefore, unless otherwise stated, it is recommended that you purchase your usual size.
4) Loafers and Ballet Flats
This is the riskiest group in terms of fit because there is usually no way to adjust the laces or elastic. They need to fully hug the foot. Leather versions stretch over time; even so, it is important that they do not “swim on your feet” at first.
Section 4: Pre-Order Mini Checklist
A 30-second check before confirming your cart can significantly reduce return-related stress:
- Is there a fit note in the product description? (Narrow fit, wide fit, etc.)
- What is the material? Leather adapts somewhat; synthetic surfaces generally stretch less.
- Are the return/exchange terms clear? Are the shipping, timeframe, and process transparent?
Section 5: The “Professional Try-On” Routine When Your Order Arrives
The moment you open the box, it is important to try them on in a way that preserves your right to return them.
- Try them on over a carpet. Do not step on surfaces that could soil the shoe soles.
- If possible, try them again in the evening.
- Walk inside for 5–10 minutes:
- Does the heel slip out?
- Are your toes hitting the front?
- Is there pressure across the instep?
- If there is a suspicion of a manufacturing defect or fault in the product, photograph it immediately.
Section 6: The Return and Exchange Process: Know Your Rights, Reduce Stress
In Turkey, consumers have the right to withdraw from distance sales contracts within 14 days without giving a reason or paying a penalty.
- For goods, the period generally starts on the day the goods are received.
- The seller is obliged to refund the payments collected within a specified period after receiving the notice of withdrawal.
Return shipping costs: “Preliminary information” is decisive
In practice, return shipping costs may vary depending on the seller’s preliminary information text and the carrier they specify; moreover, since regulations also include changes that may have implications as of 2026, consumers should pay particular attention to reading this section before placing an order.
Critical practical tips for returns
- Do not wear the shoes outdoors.
- Make sure you return the product in “resalable” condition, with its box, brochures, etc.
- Do not tape the shoe box directly; protect it with an outer box or bag.
Section 7: The Most Common Mistakes (And Easy Solutions)
Mistake 1: Buying a small size thinking, “They’ll stretch over time”
Leather mostly adapts in width; it does not work miracles lengthwise. If your toes touch the front, that size is risky. We recommend returning them and getting one size larger.
Mistake 2: Trying on only one shoe
Feet are not symmetrical. Try on both shoes and walk around.
Mistake 3: Missing the return deadline by saying, “I’ll look at it later”
14 days pass quickly. Do not delay your decision; try them on within the first 2–3 days and make up your mind.
