Most size systems are confusing, full of outdated charts, inconsistent country conversions, and brand-to-brand differences that leave you guessing.

UCXS® does it differently. Instead of forcing you into generic tables, UCXS® sizing is built on real biomechanics and biometrics.

For sneakers, you enter your foot length, and the system places it inside the UCXS® Comfort Band & Sweet Spot Zone to recommend your exact size. For clothing, UCXS® calculates a Reference Point (RP) from your height, weight, and waist (if needed), so the size reflects your build, not just a label.

It may sound complex, but it’s effortless in practice: just use the UCXS® AI Size Finder, enter your details and you’ll instantly get:

• Your exact size recommendation
• Options at boundaries (Snug or Relaxed)
• A clear fit & feel indication of what to expect when wearing

Why it Works

• Unisex by design → same logic for everyone.
  
• Accurate in cm, inches, kg, or lb → no broken conversions.
  
• Future-proof → the first system built on science, not tradition.
  
• Super easy → advanced under the hood, but effortless to use.
