K Slims are by far some of the best fitting pants i've ever owned. My only complaint is that the 3 pairs i have all feel very different. I have a pair of the dark indigo jeans that are very stretchy (similar to sweat pants), a brown pair that has slightly less stretch and black pair with hardly any stretch even though all of the pants list the same fabric blend. The pants are very durable and have shown no signs of wear even though i have skated (and fell) quite a bit. I like them so much that i placed another order for the dark indigo (they do bleed a bit, beware if you sweat a lot and have a white tshirt), a grey pair and a pair of the EE Slims since they have the same fit with a more tapered cuff.
