Jeans foot  #8 is especially suited for sewing straight-stitched seams in tough, heavy fabrics such as denim, linen or canvas. Multi-layered fabrics also benefit from the special design. 

When combined with the straight-stitch plate and its narrow needle opening, which gives the needle the greatest possible stability, the flat sole of this foot makes it easier for the foot to glide over the thick layers of fabric. It is also ideal for straight-stitching on medium weight and thin materials.
