- Which is better for backpacking with a heavy pack?
- The Lowa Zephyr GTX Mid TF. Its DuraPU midsole and stability-focused cross sole handle load better, and it takes orthotics. The Scarpa Rush TRK is better suited to lighter day packs.
- Which boot lasts longer?
- The Lowa generally lasts longer. Its split leather and polyurethane midsole resist compression better than the Scarpa's EVA midsole, which packs down sooner with heavy use.
- Is the Scarpa worth it over the Lowa?
- Only if you want a lighter, insulated fall boot with a softer EVA ride. The Lowa wins on review volume, orthotics support and lug depth, so it is the safer buy for most hikers.
- Which is better in cold weather?
- The Scarpa Rush TRK GTX. It is listed as insulated, while the Lowa Zephyr is a non-insulated 3-season boot.
- Can I use my own insoles in either boot?
- Yes in the Lowa, which is listed as orthotics compatible. The Scarpa is not listed as orthotics compatible, so check the fit with your insole before buying.
- Which has better grip on wet rock?
- The Lowa's 4.7 mm lugs bite deeper in mud and loose ground. The Scarpa's SuperGum compound is softer and grips well on smooth rock, so it is close.
