We work very hard to keep our sizing consistent across our collection, and most of our styles fit true to size. But for a true size 5 1/2, it can be difficult to know whether to order the size 5 or size 6.
For sandals, we recommend sizing down to size 5 and for closed-toe shoes, we recommend sizing up to the 6. We are always working to expand our size offering, but for now, this general rule of thumb will work for most people.
And if you are able, it's a good idea to order both sizes 5 and 6, and return the pair that doesn't fit for a refund. With our 30-Day Guarantee and flat rate shipping, there is no additional cost to doing this.
