Measure
Start from the usual size
Use the current professional shoe as a reference, then fine-tune with the test pair.

Fit guide
Professional footwear has to hold up through long shifts, swelling feet and different habits. The right test process heads off most mistakes.
Adjustment
No two people wear shoes the same way. Insoles, socks, shift length and floor type all shape the final fit. Comparing 105 EUR to 75 EUR misses the point ; the annual cost per wearer is what counts.

Measure

Test
Feedback after two hours is not the same as feedback after a full service.
Adjust
The insole can fine-tune fit and comfort before you confirm a size run.
Proof points
Simple questions make the feedback easier to compare. For a reception team of 8 over three years, the figures land at 3,100 EUR with Karl & Max against 5,520 EUR with a synthetic pair : a saving of 2,420 EUR, about 100 EUR per wearer per year.
Any pressure on the toes or instep?
Any slipping at the heel?
How do the feet feel at the end of service?
Would they wear the same pair again tomorrow?
