Anivia Boots bug

As you can see from the image, I was playing anivia, and you can clearly see the magical footwear rune in the bottom left corner. However, for some reason, no boots appear in my inventory. Furthermore, my movement speed is marked as 325, which is anivia's base MS. I'm not really sure how to recreate it, but I can go through the game video if it would help. Not really sure what to do next :/
