A step-by-step guide to sizing the Türnberg SOPO kids slippers, checking fit for growing feet, and handling the first wear so wool house shoes stay comfortable.
Quick answer
Measure your child's foot in the afternoon, add about 1 cm of growing room, and choose the Türnberg SOPO size that matches that total length. Then check the elastic grip and toe space with the slipper on before letting your child wear it for a full day.
Why the elastic and sole change how you size
The Türnberg SOPO uses an elastic band to hold the slipper on and a soft rubber sole that flexes like barefoot walking. That means the fit should feel secure around the instep without pressing, and the sole should bend with the foot rather than force the toes into a rigid shape. If you size only by age or by the length printed on another brand, the elastic can mask a slipper that is too long or too short.
Wool also behaves differently from synthetic linings: it warms the foot and moves moisture away, so a slipper that feels slightly snug at first can become more comfortable as the wool adapts. Still, you should never rely on stretch to fix a slipper that is clearly too small.
When to size up and when not to
Growing room matters, but too much length makes the elastic work harder and can cause the heel to slip. A useful rule is to leave roughly a thumb's width (about 1 cm) beyond the longest toe for toddlers and younger children. For older kids who wear slippers mostly indoors and are between sizes, choose the smaller size if the larger one lets the heel lift out when walking.
If your child has a high instep or wide feet, the elastic may feel tight across the top even when the length is right. In that case, check that the slipper can be pulled on without curling the toes, and consider whether a different model in the range suits the foot shape better.
Step-by-step: fit and first wear for the Türnberg SOPO
- Measure the foot in the afternoon: Place a sheet of paper on the floor, have your child stand on it with the heel against a wall, and mark the longest toe. Measure from the wall to the mark in centimeters. Do this in the afternoon, when feet are slightly larger than in the morning. Write the measurement down and use it for both feet; one foot is often a few millimeters longer.
- Add growing room, then match the size: Add about 1 cm to the longer foot measurement for toddlers and younger children, or 0.5–1 cm for older kids who are between sizes. Compare that total to the slipper size chart, and if you are between two sizes, choose the smaller one when the larger size lets the heel lift. Do not size up more than one step just to extend wear time; too much length defeats the elastic hold.
- Check heel hold and toe space with the slipper on: Put the slipper on your child and press gently at the toe to confirm there is about a thumb's width of space beyond the longest toe. Ask your child to walk a few steps; the heel should stay in place and the elastic should not leave red marks or slip off. If the heel lifts or the elastic leaves marks, try the other size before wearing them outdoors or for a full day.
- Do a short first wear indoors: Let your child wear the slippers for 20–30 minutes indoors on the first day. Check for rubbing at the heel or across the instep, and look at the skin for pressure points. Wool can feel warm quickly, so watch for signs of overheating or discomfort. Stop and remove the slippers if your child complains of pressure; a different size is usually the fix.
- Extend wear time gradually: Increase wear by about an hour per day over the first week, always indoors. This gives the wool and elastic time to adapt to the foot and lets you spot any fit issue before it becomes a habit. Keep the first week indoors only; save longer wear for after you have confirmed a comfortable fit.
- Recheck the fit every few weeks: Repeat the toe-space check every 4–6 weeks, especially for toddlers and preschoolers. Children's feet grow in spurts, and a slipper that fit last month may now be too short. If the thumb's width is gone, move up a size. Mark the date of each check on a calendar so you do not rely on memory.
Product facts that affect fit
- Türnberg SOPO: The Türnberg SOPO has an elastic band for secure hold and easy on-and-off. A secure elastic makes first wear simpler, but it also means you should check that the band is not digging in or leaving marks.
Türnberg SOPO - Türnberg SOPO: The soft rubber sole is non-slip, lightweight and flexible for a barefoot feel. A flexible sole lets you feel whether the slipper bends naturally with your child's foot instead of stiffening the step.
- Türnberg SOPO: The wool keeps feet warm and transports moisture away. Wool can feel warm from the first minute, so judge fit by length and heel hold, not by initial warmth alone.
