These pants have slits about 10cm long, starting from around the instep of both legs and going up to the hem. I purchased them last winter. You can see them in the first photo. They are straight-leg, matte black (a dark charcoal gray that's easy to match with other colors) pants with an elastic waist for comfortable wear. They are also stretchy, made of thick fabric that doesn't wrinkle easily, and are warm and comfortable for fall and winter. There are no pets or smokers in the storage environment. I only use fabric softener that is either unscented or fragrance-free. - Brand: SLOBE IÉNA - Color: Black - Style: Straight Leg Pants - Waist: Elastic Waist Thank you for looking.
