WranglerMen's Rugged Wear Stretch Jean Stonewashed Big

Are these jeans considered bootcut or straight leg? It looks like it's a straight leg on the picture but says it fits over boots.

what is 30 L mean ? is it 3o inc long ?

Will these jeans stain where you sit with the cloth coloring ?

Are the jeans skinny jeans or are they wide leg? I'm looking for pants that kind of fit around the legs and ankles
