#50W 9mm BERNINA Three-Sole Walking Foot with Seam Guide

• With three soles for sewing, quilting and topstitching.
• Perfect fabric feed and even stitch formation.
• Seam guides help you sew with precision.
• Materials that are stretchy or tend to stick.

The BERNINA #50W Three-Sole Walking Foot with Seam Guide is the upgrade quilters and sewists with new-style 9mm machines have been waiting for. It feeds the top and bottom layers of fabric at exactly the same rate, eliminating the shifting, puckering, and misalignment that standard presser feet cause when working with layered, slippery, or sticky materials.

Whether you're machine quilting, matching stripes and plaids, sewing vinyl or leather, or topstitching through multiple layers, the #50W handles it with precision.

Three interchangeable soles:

• Standard sole — everyday sewing and general use
• Quilting sole — ideal for machine quilting through quilt sandwich layers
• Central guide sole — perfect for edge stitching and stitching in the ditch

Two seam guides keep your seam allowances consistent from start to finish — no measuring, no drifting.

The BERNINA #50W Three-Sole Walking Foot with Seam Guide is designed specifically for new-style BERNINA 9mm stitch-capable machines. Just released, this accessory finally allows sewists to utilize the full 9mm maximum stitch width for decorative and zigzag patterns while maintaining even fabric feeding.

Key Improvements Over the Legacy #50 Foot

• Stitch Width Expansion: The previous legacy #50 foot restricted stitching width to 5.5mm. The new #50W lets you sew decorative stitches, jumbo stitches, and wide zigzags at a full 9mm.
• Feed Dog Optimization: The bottom soles are completely redesigned and widened to perfectly match and cover the wider feed dogs found on modern 9mm machines. This maximizes traction and fabric control.

 Interchangeable Soles & Accessories

The attachment functions as a complete system, including three interchangeable soles and two adjustable seam guides:

• Standard Closed-Toe Sole: Best for everyday utility sewing, straight lines, matching plaids, and working with slippery or sticky materials like vinyl.
• Open-Toe / Quilting Sole: Offers maximum visibility directly in front of the needle, making it ideal for machine quilting and intricate applique work.
• Central Guide / Edge Stitching Sole: Features a built-in center guide strip perfect for precise stitch-in-the-ditch quilting or clean topstitching right along a fabric edge.
• Left & Right Seam Guides: Easily attach to the back of the walking foot assembly to act as parallel alignment rulers for evenly spaced rows of accent stitching or straight-line quilting grids.
