UGG dropped a big surprise with a new collaboration that takes a step back from the cozy boots its famous for. In a collaboration with Tokyo-based fashion brand AMBUSH , UGG dropped two new shoe styles — an UGG AMBUSH Mary Jane ($250) and an UGG AMBUSH Loafer ($225). The new styles aren’t like anything we’ve seen before from UGG, with a sheepskin upper on the classic Mary Jane style and a fur plug filling out the upper portion of the traditional Loafer.

UGG is offering the AMBUSH Mary Jane in two colors — Pink and White. Both have a Black toe peaking out and an AMBUSH metal Heart snap in a finishing detail. But this unique style is selling out fast with only select sizes available at the time of writing.

The UGG AMBUSH Loafer is an all-gender design that’s available in Black and Burgundy. This unexpected loafer style features warm sheepskin inside the shoe and is finished with a fitting AMBUSH Coin detail. Both shoes also feature the UGG and AMBUSH logos, signifying the new UGG collaboration with designer YOON, who leads the AMBUSH brand.

But because this new UGG AMBUSH Collection is a new take on the Mary Jane and Loafer styles that we’ve grown to love, we know it’s only a matter of time before they’re sold out. So, grab them now while you can, so you don’t have to wait for a potential restock. Snag the brand new UGG AMBUSH Collection Here’s where to grab the new UGG AMBUSH Collection while you still can.
