Choosing trail running shoes often means balancing weather protection, terrain grip, fit, and price. A waterproof pair may suit a wet route, while a hiking-oriented approach shoe can make more sense for mixed outdoor use; pre-owned condition may be the tradeoff for a lower price. Here's how four specific pairs divide those decisions so you can match the shoe to your use case instead of chasing one universal winner.
Quick take
Start with your non-negotiable: lower price, wet-weather protection, hiking or approach use, a women's or men's fit context, or new versus pre-owned condition. The price table narrows the money question; the decision matrix sorts the main fit and condition splits; the notes explain the concrete reason and limitation for each pair.
Listed-price comparison
The four prices have a $117.99 spread from lowest to highest. That gap makes intended use and condition worth weighing alongside trail-focused features.
| Product | Listed price | Price bar |
|---|---|---|
| Scarpa Zen Pro Women's | USD 37.50 | |
| Scarpa Zen Pro Men's | USD 32.00 | |
| Salomon Speedcross 6 GTX W | USD 149.99 | |
| Merrell Agility Trail Waterproof | USD 77.50 |
Decision matrix
- Price first: Compare the two Scarpa Zen Pro pairs; the men's entry is lower than the women's entry, while Salomon sits at the top of the range and Merrell falls between them.
- Wet-weather construction: Salomon Speedcross 6 GTX W and Merrell Agility Trail Waterproof are the two names that explicitly identify waterproof protection.
- Condition: The Scarpa pairs are pre-owned-one Excellent and one Good-while Salomon and Merrell are new with box.
- Fit context: The women's entries are the Scarpa US 9.5 pair and Salomon Sz11. The men's entries are the Scarpa 7.5 / 40 pair and Merrell's men's shoe.
Product notes
Scarpa Zen Pro Green Orange Technical Trail Shoes - Women's 9.5

The women's Scarpa Zen Pro is a clear fit for hiking with climbing gear. Its lightweight approach-shoe design is paired with a sturdy suede and breathable air-mesh upper, a P-Flex footbed, an injected EVA midsole, and a Vibram Spyder 2 sole. That combination keeps the use case centered on hiking and approach movement. The limitation is condition: pre-owned-excellent. Choose it when climbing-gear hikes and the women's Zen Pro profile match your plans; look elsewhere when pre-owned footwear is not acceptable.
Scarpa Zen Pro Green Orange Technical Trail Shoes - Men's 7.5 / 40

The men's Scarpa Zen Pro is the price-led choice for shoppers who want the named Scarpa Zen Pro model at the lower end of this comparison. Green color, standard width, sneaker styling, and hiking activity give it a straightforward outdoor brief. The limitation is condition: pre-owned-good. Its title also frames the pair around a men's size context, so fit remains a specific part of the decision. Choose it when lower outlay, the Zen Pro model, and hiking use matter most; choose another pair when new-with-box condition is the deciding requirement.
Salomon Speedcross 6 GTX W Ortholite - Women's Sz11

Salomon Women's Speedcross 6 GTX W is aimed at shoppers who want a technical trail running shoe with GTX and Ortholite named in the product title. The pair also has a rubber outsole, drawstring closure, and features including breathable, cushioned, lightweight, moisture-wicking, motion-control, and slip-resistant characteristics. The concrete limitation is price: $149.99 is the highest listed amount in this comparison. Choose it for the GTX and Ortholite combination and technical-trail positioning; choose another pair when that top price does not fit your spending limit.
Merrell Agility Trail Waterproof - Men's Mariana Blue

Merrell Agility Trail Waterproof is a match for shoppers seeking off-road movement with cushioning and ground connection in the brief. FloatPro foam, FLEXconnect grooves, a 3mm lug outsole, and rubber cleat type are named, while the Mariana Blue color and lace-up closure make the pair easy to distinguish. The limitation is fit context: the title specifies men's footwear, and shoppers wanting a drawstring closure may prefer the Salomon instead. Choose Merrell when those trail-oriented cushioning and traction details fit your route; look elsewhere when the men's format or lace-up setup is not right.
Final recommendation by use case
- For wet conditions: Choose Salomon Speedcross 6 GTX W or Merrell Agility Trail Waterproof. Both explicitly identify waterproof protection. Salomon suits shoppers drawn to GTX, Ortholite, and a drawstring closure; Merrell suits those who prefer FloatPro, FLEXconnect, and a lace-up setup.
- For hiking with climbing gear: Choose the women's Scarpa Zen Pro, whose approach-shoe wording and hiking-with-climbing-gear use make the purpose clear.
- For the lowest listed price: Choose the men's Scarpa Zen Pro at $32, provided its pre-owned-good condition and men's fit context work for you.
There is no single winner across these four trail running shoes. The Scarpa pairs focus the decision on price and hiking use, Salomon combines technical-trail and waterproof positioning at the top price, and Merrell offers a waterproof trail-running direction with named cushioning and ground-connection features.
