The Nike x Liberty collections are always very popular and I think this collection won't be an exception either. The sneakers and clothes are from the spring/summer 2015 collection. And because of the fun, colorful prints, they indeed look great for summer. Of course you can use them to spice up your outfit during fall and winter as well.
I absolutely love the Nike Air Max Thea from this collection. I also really like the Nike Liberty Classic Cortez (fourth picture).
