A little more fit confidence
Before you step in.
How do I choose my arch height?
Take the 45-second arch test to find your low, medium or high profile. If you already know your arch, choose it directly above. Stretta offers medium-arch support in a narrower shape.
Will Stretta fit my shoes, or should I choose Medio?
Choose Stretta for medium-arch support in a narrower fit. It's designed for narrow feet and lower-volume footwear, including many women's athletic shoes, narrow-width shoes and shoes built on a narrow last (a slimmer shoe shape). Its heel, midfoot and forefoot are narrower than Medio's.
For medium-arch support in a standard-width shape, choose Medio. Both profiles offer men's and women's size labels, so choose by your foot and shoe fit.
What if I wear a half size?
Conforma comes in full sizes that fit the half size above. A size 8 insole fits a size 8–8.5 shoe. Select men's or women's US sizing to see the matching sizes.
Do I remove the insole already in my shoe?
Yes. Remove the factory insole before inserting Conforma. It replaces your stock insole; it doesn't sit on top. For narrower shoes, consider Stretta if you have a medium arch.
Is Conforma custom-made for me?
Conforma is an over-the-counter insole: you choose a ready-to-wear, pre-molded profile to match your arch height. For an orthotic precision-milled from a scan of your own foot, choose full custom.
Can I return them after wearing them?
Yes. All online orders include a 30-day wear test. Return your pair within 30 days for a refund of the product price, with no restocking fee. You pay return shipping. Read the returns policy →
More about Conforma Stretta
The Classic Stretta Insole is designed to deliver all-day comfort, stability, and performance in a slimmer profile. Built on the Medio arch profile with a narrower heel, midfoot, and forefoot, the Stretta is ideal for feet and footwear that require a more precise fit.
Originally developed for women's shoes, we discovered this streamlined shape also performs exceptionally well in lower-volume footwear such as soccer cleats, cycling shoes, hockey skates, and other narrow-fitting shoes. Stretta is the Italian word for narrow—and that's exactly what this insole delivers.
