How to choose your size and get a comfortable fit in the JERBA-137 yellow flat sandal, with clear decision rules for width, arch support and all-day wear.
Quick answer
Choose your usual size in the JERBA-137 if you have an average-width foot and want a simple slip-on flat. If you are between sizes or have a wider forefoot, size up rather than expecting the sandal to stretch into shape.
Why the JERBA-137 is easy to size but not universal
The JERBA-137 is a flat sandal with a simple design and a flexible structure, so there is little hardware or stiffness to complicate the fit. That makes it a low-risk choice for most people who already know their usual sandal size. The limit is that the catalog does not list width options or a specific arch profile, so you cannot fine-tune the fit the way you might with a laced or adjustable style. Treat your usual size as the starting point, then use the rules below to decide whether to size up.
Where a flat sandal can feel wrong even in the right length
Length is only one part of fit. In a flat sandal, the two common problem areas are the forefoot width and how the sole meets your arch. If the sandal feels tight across the toes but your heel sits correctly, going up a size can help, but it may leave extra length at the back. If the sandal feels loose across the top but the length is right, the issue is usually volume rather than size. The JERBA-137 has a flexible structure, which helps it follow the foot, but flexibility is not the same as adjustability. Decide which problem you actually have before changing size.
Decision rules for choosing your JERBA-137 size
- Start with your usual sandal size: If you have an average-width foot and your current flat sandals fit well in length, order the same size in the JERBA-137. The simple, flexible construction gives you little reason to deviate from your normal size.
- Size up if you are between sizes: When one foot measures at the top of one size and the other at the bottom of the next, choose the larger size. A flat sandal that is slightly long is easier to live with than one that presses on the toes. Check both feet, not just the larger one, before deciding.
- Size up for a wider forefoot: If you regularly need a wide fit or feel pressure across the toes in standard sandals, go up one size in the JERBA-137. The catalog does not list a wide-width option, so extra length is the only available adjustment.
- Do not size down for a looser feel: If the sandal feels roomy across the top but the length is correct, sizing down will usually make the toes feel cramped. Keep your size and use the fit check below instead.
- Check the fit at the end of the day: Try the sandal on in the afternoon or evening, when feet are at their largest. Walk on a hard floor for a few minutes and confirm that your heel stays on the sole and your toes do not touch the front edge. If your toes touch the front edge, go up a size.
