Learn how to dial in the fit of the Timp 6 Mid GTX and keep its GORE-TEX protection working on wet trails with this step-by-step guide.
Quick answer
Start with your usual running shoe size, lace the mid-ankle collar snug without restricting your ankle, and clean and reproof the GORE-TEX upper after every wet, muddy run. These three habits give you a secure, waterproof trail shoe that lasts.
Why the mid-ankle design changes your fit check
The Timp 6 Mid GTX adds a mid-ankle collar for support, so the fit is not just about toe room. A collar that is too loose lets debris in and reduces stability; one that is too tight can rub or restrict your ankle on descents. Lace and re-lace the upper before you commit to a size.
Waterproof care is about keeping the membrane clean, not just dry
GORE-TEX keeps water out, but mud and grit can clog the outer fabric and reduce breathability. Rinse the shoe after every wet run, and use a soft brush on the upper. Avoid heat and harsh detergents, which can damage the waterproof membrane and adhesives.
Step-by-step fit and care routine
- Start with your usual running shoe size: Try the Timp 6 Mid GTX in the same size as your everyday trail running shoes. The mid-ankle collar should feel snug but not tight, and you should have a thumb's width of space at the toe. If the collar presses or gaps, adjust the lacing before sizing up or down.
- Lace for ankle support and heel lock: Use the closed eyelet hardware to create a secure heel hold. Lace from the bottom up, keeping tension even across the midfoot. At the top, tie a heel-lock loop if your ankle feels loose. Re-check lace tension after 10 minutes of walking; feet swell and laces can loosen.
- Test the fit on a short trail run: Wear the shoes on a 20–30 minute run that includes climbs and descents. Pay attention to heel lift, toe pressure, and ankle rub. If you feel hot spots, adjust lacing or try a different size. Never take a new pair on a long wet run before a short test; blisters are harder to manage in the rain.
- Clean and dry after every wet run: Rinse mud off with cool water, brush the upper gently, and remove insoles to air-dry at room temperature. Stuff with newspaper to absorb moisture. Never use a dryer or direct heat. Drying properly preserves the GORE-TEX membrane and prevents odor.
- Reproof the upper when water stops beading: When water no longer beads on the fabric, apply a GORE-TEX-approved repellent spray or wash-in treatment. Follow the product instructions and let it cure fully before wearing. Reproofing extends the life of the waterproof layer; test by sprinkling water on the toe.
