Wide Toe Box & Wide Width Shoes, Built For You

Standard shoes are too narrow, compressing feet, and "wide" labels rarely fix the part that matters: the toe box. When toes can't spread naturally, it costs you both comfort and a stable base to stand on. SOULIA addresses that at the source: 3D-printed from your exact foot shape, for a fit that's genuinely custom.

Every Foot Has A Different Width

3 different widths per shoe size would be needed to properly fit 90% of the population.

Jurca, Žabkar & Džeroski, Scientific Reports, 2019

Analysis of more than one million 3D foot scans by Volumental reveals a striking reality: foot shapes vary so much that a single shoe width can never fit everyone.

Squeezing feet into a space that's too narrow tends to encourage rubbing, calluses, and pressure points, especially for extra-wide feet.

SOULIA Fits Your Exact Width

3D-printed from a scan of your feet, SOULIA adapts to your exact width for a genuinely custom fit, not a shoe stretched wider from a standard last.

Paired with a wide toe box, this design helps free your toes from the narrowness of standard shoes, letting them spread naturally instead of staying compressed into a fixed shape.

This also prevents tight squeezing across the forefoot, ensuring your circulation is never restricted.

Common Questions About Fit & Width

What's the difference between wide width and a wide toe box?

Most "wide" shoes simply add width evenly across the whole shoe, which often still leaves the front of the foot compressed.

A wide toe box specifically targets the front of the shoe, giving toes the room to spread naturally, while wide width addresses the overall volume of the shoe.

SOULIA combines both, tailored to your exact foot shape:

  • Initial 3D scan: Captures your foot's actual width and shape, not a standardized size chart.
  • Wide toe box: Gives your toes room to spread instead of staying compressed into a pointed or tapered shape.
  • Custom width: Matches the shoe's volume to your foot, rather than stretching a standard last wider.

My feet swell or change size during the day, will these still fit?

Yes, as foot volume can genuinely change throughout the day, SOULIA's custom width is designed to give your foot the base room it needs, which can help reduce tight spots as your feet swell.

If you experience significant daily swelling, we recommend scanning your feet at the time of day when they're typically at their largest.
