Felting Patons Regency Classic Merino Wool help

has anyone done this? i am going to make the warm woolies booties with this… how much shrinkage can i expect? thanks
this is the colorway:

I made a pair of mittens with this colorway, they turned out really well! I wish I had a picture.

I didn’t intend for them to be felted, but I had made them a tad too loose, so felted them briefly to shrink them down. Patons, in general, felts relatively quickly. (Sorry, I wish I could be more specific). :??
