Learn how to measure your foot and select the right size for the Women's OOahh Sport Flex Sandal. Avoid common sizing mistakes with this step-by-step guide.
Quick Answer
Measure your foot length in centimeters while standing, then compare to the OOFOS size chart for the Women's OOahh Sport Flex Sandal. If between sizes, size up for a comfortable recovery fit.
Why Accurate Sizing Matters for Recovery Sandals
The Women's OOahh Sport Flex Sandal uses OOfoam™ technology to absorb impact and reduce stress on joints. A proper fit ensures the arch support lines up correctly and the strap holds your foot without rubbing. Too loose and you lose support; too tight and the foam can't work as intended.
Key Differences from Other OOFOS Slides
Unlike the classic OOriginal slide, the Sport Flex features an adjustable upper strap for a more customized fit. This means you have more control over how the sandal feels around your instep, but the footbed length sizing remains the same across OOFOS slide models. If you've worn other OOFOS slides, your size is likely the same, but always measure to be sure.
Step-by-Step Sizing Guide
- Measure Your Foot Length: Place a piece of paper against a wall. Stand on it with your heel touching the wall. Mark the longest point of your foot (usually the big toe or second toe). Measure the distance from the edge of the paper to the mark in centimeters. Repeat for both feet and use the longer measurement. Common mistake: measuring while sitting. Your feet spread under weight, so standing gives the true length.
- Compare to OOFOS Size Chart: Find your foot length in centimeters on the official OOFOS size chart for slides. The chart typically lists US and EU sizes alongside CM measurements. Select the size that corresponds to your measurement. If your foot length falls exactly on a boundary, choose the larger size. Checkpoint: The size chart is the same for all OOFOS slide models, so you can use it for the OOahh Sport Flex Sandal without confusion.
- Adjust the Strap for Final Fit: Once you receive the sandal, slide your foot in and tighten the adjustable strap so it holds your foot securely without pinching. Your heel should sit slightly inside the heel cup, and your toes should not overhang the front edge. Walk a few steps; if your foot slides forward, the strap is too loose or the size is too large. Common mistake: over-tightening the strap to fix a size that's too big. The strap is for fine-tuning, not for correcting a full size mismatch.
