Before picking your pair, step down onto a flat piece of paper, trace your heel and longest toe, and measure the distance in centimeters. Match your measurement against the Sharkicks Pro size chart below to identify the intended bracket.
| Molded EU Size | US Women's Size | US Men's Size | Barefoot Length (Inches / CM) | Fit Character |
|---|---|---|---|---|
| 36, 37 | 5.5, 6.5 | 4.0, 5.0 | 9.05 in / 23.0 cm | Snug heel cup, true to length |
| 38, 39 | 7.0, 8.0 | 5.5, 6.5 | 9.45 in / 24.0 cm | Standard medium volume |
| 40, 41 | 8.5, 9.5 | 7.0, 8.0 | 9.84 in / 25.0 cm | Moderate midfoot taper |
| 42, 43 | 10.0, 11.0 | 8.5, 9.5 | 10.23 in / 26.0 cm | Accommodating toe box |
| 44, 45 | 11.5, 12.5 | 10.0, 11.0 | 10.63 in / 27.0 cm | Generous wide-foot allowance |
For individuals wearing a US Women's 8.5 or a US Men's 7.0, the EU 40, 41 tier provides approximately 6 to 8 millimeters of clearance ahead of the toes. This margin prevents your toenails from impacting the internal ridge when stepping down inclines or walking briskly outdoors.
