Not sure of the sale dates, but I heard up to 60% off selected MountainDesign products on Nova. Checked website, and noticed some good discounts on some products.
The link should take you to their sale products, and the check boxes on the left provide good filters.
Only one small problem - what measurement system is used for the footwear? It would have been a great idea for the site to offer conversion tables. Assume euro for the sandals I checked out? Or did I miss it somewhere? Boots are a different size system too.
