Kanye had a MELTDOWN when Kylie Jenner signed up to Puma, and it looks like he might just have another little meltdown since the Jenner sisters are now designing their own range of trainers.

The KUWTK stars shared a sneak peek on Kylie's Snapchat of their new SS17 Kendall + Kylie line, and we have to say, it was unexpected.

In their latest collection out now, the girls flooded the line with strappy sandals and high heels, but these runners are cool and stylish and right up our alley (in case you haven't noticed, our alley is COMFORT).

All we want to know is if these are the only athleisure pieces in the collection (oh, and what Kanye thinks about it).

We'll have to wait a while to find out!
