It asks questions and then makes a recommendation. The recommendation was spot on for me and I picked it for purchase. The shoe arrives 4 sizes too large. I double check the order and find that although the recommendation is spot on it defaults to ordering 4 sizes larger. I see no way to order the correct size and am now paying over $5 to return. Shame on me for not catching it.

WARNING: DON'T MAKE THE SAME MISTAKE AS ME.
