Learn how the Women's AeroPro 3" Split Shorts fit and perform. This guide covers sizing, the 3" inseam with half-side splits, and the low-profile waistband for a chafe-free run.
Quick answer
The Women's AeroPro 3" Split Shorts deliver a lightweight, high-mobility fit for runners who want a 3" inseam with half-side splits. Use this guide to confirm your size and dial in the waistband for a no-slip, chafe-free run.
Why the 3" inseam and half-side splits matter for fit
The 3" inseam is a popular choice for runners who want coverage without restricting leg movement. The half-side splits add extra freedom, allowing a full range of motion during strides and sprints. The key is that the splits are designed to stay flirty, not flashy—they open just enough to move without exposing more than you want. If you prefer a shorter or longer inseam, consider other options in the BOA line.
The waistband: low-profile and adjustable
The low-profile 2" perforated waistband is engineered to keep you cool as you heat up. Perforations allow airflow, reducing moisture buildup. The flat drawcord lets you lock in the fit without adding bulk. A common fit issue is over-tightening the drawcord, which can cause the waistband to roll or pinch. Instead, snug the drawcord just enough to hold the shorts in place without digging in.
How to find your fit in the AeroPro 3" Split Shorts
- Measure your waist and hips: Use a soft tape measure around the narrowest part of your waist and the fullest part of your hips. Compare your measurements to the BOA size chart. The waistband should sit at your natural waist without gaping. Common mistake: relying on your usual clothing size instead of measuring. The AeroPro waistband is fitted but not compressive, so accurate measurements matter.
- Check the inseam length: The 3" inseam is measured from the crotch seam to the hem. If you are between sizes or prefer a slightly longer or shorter feel, try the shorts on and do a few lunges or high knees. The half-side splits should not ride up excessively. Checkpoint: if the hem rises above your comfort zone during movement, consider a different inseam length rather than sizing up.
- Adjust the flat drawcord: Tie the drawcord in a flat knot or bow. The cord lies flat against the waistband to prevent chafing. Tighten only until the shorts feel secure—over-tightening can cause the perforated waistband to bunch or roll. Common mistake: pulling the drawcord too tight, which can create pressure points and reduce the cooling effect of the perforations.
