When deciding what size to get I was stuck between the 38 and 39. In most shoes I’m a solid 8.5 or EU 39. So I bit the bullet and went for the 39! Alas, they arrived and my foot looked so small in the 39’s. I snapped a photo and sent it in to the customer service email and they were super helpful and told me a 38 would fit perfectly! The return was smooth and easy and I got the right size quickly! They fit great now, and I’m so excited to wear them everyday this summer!
