Get a secure, dry fit from the women's Torin 9 GTX with a step-by-step sizing, lacing, and waterproof check for wet-weather road runs.
Quick answer
Start with your usual women's running shoe size, then fine-tune the Torin 9 GTX fit by locking the midfoot and checking that the waterproof upper flexes with your stride. If you run long in cold rain or wear thicker socks, consider a half size up.
Why the GTX upper changes the fit conversation
The Torin 9 GTX uses a GORE-TEX Invisible Fit waterproof upper with a stretchy design, so it feels different from a standard mesh road shoe. The waterproof layer adds structure and reduces airflow, which makes a precise midfoot hold more important than simply sizing up. A loose fit can let water in at the collar and cause heel slip; an overly tight fit can restrict the stretchy upper and feel stiff on longer runs.
When to size up and when to stay put
The catalog does not list a specific last or width, so use your normal running shoe size as the baseline and adjust based on sock thickness and run length. If you plan to wear thick merino socks in winter rain, a half size up may give your toes room to splay without pressing the waterproof upper. If you wear thin socks and run short, your usual size should keep the shoe secure. Always test with the socks you will actually run in.
Step-by-step Torin 9 GTX fit check
- Start with your usual running shoe size: Put on the socks you will wear in wet weather and slide your foot into the Torin 9 GTX. Stand up and press your thumb against the top of the toe box; you want about a thumb's width of space ahead of your longest toe. Common mistake: sizing up automatically because the shoe is waterproof. The GTX upper does not automatically run small, so start with your normal size and only adjust if your toes touch the front. Check toe space with your running socks on, not bare feet.
- Lock the midfoot with a runner's loop: Lace the shoe normally up to the second-to-last eyelet, then create a runner's loop by threading each lace back through the top eyelet on the same side before tying. This pulls the stretchy upper snugly around your instep without crushing the toe box. Common mistake: over-tightening the bottom laces to compensate for a loose heel. Keep the lower laces relaxed and use the runner's loop to secure the heel. If your heel lifts, add a runner's loop before tightening the whole shoe.
- Test the waterproof collar seal: Walk around indoors and flex your ankle. The padded collar should sit close to your ankle without rubbing, and the tongue should stay centered. A gap at the collar lets rain run down your leg and into the shoe. Common mistake: leaving the top eyelet unlaced for comfort. On wet runs, lace all the way up to keep the collar sealed against splashes. A secure collar is your first defense against water entering from above.
- Do a wet-surface flex test: Take the shoe outside on a damp sidewalk or driveway and do a few short runs and turns. The stretchy upper should flex with your foot without pinching, and the Vibram XS DURA outsole should feel planted. Common mistake: only testing indoors on carpet. Wet pavement reveals slipping inside the shoe or a loose heel that dry floors hide. If you feel slipping or pinching on wet pavement, adjust lacing or size before your first long run.
Product facts
- Women's Torin 9 GTX: Lightweight GORE-TEX Invisible Fit waterproof upper with a stretchy design. The waterproof membrane keeps rain out but needs a snug midfoot fit to avoid pooling at the collar and heel.

Women's Torin 9 GTX - Women's Torin 9 GTX: Vibram XS DURA rubber outsole is described as 8.5% grippier than the Torin 8. Better wet-road traction means you can trust the shoe on slick pavement once the fit is locked in.
