Size Guide
How to Find Your Size
- Stand on a flat piece of paper with your heel against a wall.
- Mark the tip of your longest toe and the back of your heel.
- Measure the distance between the two marks in inches or centimeters, then find your size below.
Your usual size is a starting point. If you are between sizes or prefer a roomier fit, choose the larger size. Foot length is the most accurate way to find your fit.

Why Choose FLEX Astra?
Foot Pain Relief in a Boot
Cute boots and pain relief haven’t always gone hand-in-hand, but they do in this little number. FLEX Astra packs superior arch support, shock absorbing cushion, and our industry-leading KURUSOLE technology, which dynamically flexes to hug and protect the most punished part of the foot: the heel.
Chelsea Goes Flexy
This isn’t just any Chelsea boot. We kept the look but threw out the flat soles and the stiff uppers. Built on the flexible, fan-favorite FLEX Via sneaker base, FLEX Astra may just make you forget you’re wearing shoes.
Exits Made Easy
Get out the door quickly with this boot’s chic, stretchy side panels, heel pull tabs, and soft leather uppers. Just one more way FLEX Astra makes it simpler to live the life you love.
