Choosing trail running shoes means balancing the route with the details that matter before you buy: waterproof protection, an ultra-trail focus, size, packaging, and price. The four choices here split clearly between weather-oriented footwear and shoes described for ultra trail running, with men's and women's sizing also shaping the decision.
Quick take
- For wet-weather routes: Salomon and Merrell are the clearest choices because waterproof wording appears in their product information.
- For ultra-trail emphasis: Fuga EX3 is specifically described for ultra trail running, while the adidas Terrex Soulstride title includes "Ultra Trail."
- For a lower listed price: Merrell starts the comparison at the lowest amount.
- For box condition: Salomon, Fuga, and Merrell are marked new with box; adidas is marked new without box.
Listed-price comparison
The prices cover a wide spread, so the right choice depends on whether features, a specific size, or a lower outlay leads the decision.
| Shoe | Listed price | Price bar |
|---|---|---|
| Salomon Women's Speedcross 6 GTX W | $149.99 | |
| adidas Men's Terrex Soulstride Ultra Trail | $94.00 | |
| Fuga EX3 Men's Trail Running Shoes | $140.00 | |
| Merrell Men's Agility Trail WATERPROOF | $77.45 |
Decision matrix
- Weather-focused running: Compare the Salomon and Merrell choices first. The Salomon is a women's size 11 model, while the Merrell is a men's Mariana option.
- Long-distance off-road focus: Fuga EX3 is described for long-distance off-road racing. The adidas title also identifies the Terrex Soulstride as an ultra-trail shoe.
- Sizing filter: Salomon is listed as women's size 11, adidas as men's size 9, and Fuga as men's US 10. Merrell is identified as a men's shoe without a size in the product name.
- Packaging preference: New with box applies to Salomon, Fuga, and Merrell. The adidas pair is new without box.
- Closure detail: Salomon uses a drawstring closure; adidas and Merrell use lace-up closures.
Product notes
Salomon Women's Speedcross 6 GTX W Ortholite /Technical Trail Running Shoes Sz11

The Salomon Speedcross 6 GTX W is a strong match for shoppers prioritizing a technical-trail model with waterproof, breathable, cushioned, lightweight, and moisture-wicking attributes. Its product information also includes non-slip and slip-resistant descriptors, plus a rubber outsole described for durability and slip resistance. The women's size 11 specification makes the choice straightforward for that size requirement. The limitation is equally specific: the model is offered here in women's size 11, with the Flint Stone/Black/Heather color and a drawstring closure. At $149.99, it also sits at the highest end of this comparison.
Adidas Men's Size 9 Terrex Soulstride Ultra Trail Running Shoes IE8453

The adidas Terrex Soulstride earns attention from shoppers who want the words "Ultra Trail" and "Terrex Soulstride" in the shoe name, along with a men's size 9 and black color. Its lace-up closure suits buyers who prefer that familiar fastening style, and the activewear positioning keeps the intended use centered on outdoor movement. The practical limitation is packaging: the pair is marked new without box. That detail may matter to shoppers who want boxed footwear for storage or gifting. The listed men's size 9 also makes sizing a central part of the decision rather than an afterthought.
Fuga EX3 Men's Trail Running Shoes Ultra Trail Running Sneakers Lightweight - 10

Fuga EX3 is the most directly described choice for ultra trail running: its description focuses on lightweight comfort and durability for long-distance off-road racing. That gives it a clear use-case connection for runners looking at extended trail events rather than general outdoor wear. The title also calls the sneakers lightweight and identifies a men's size 10, while the attributes specify a multicolor design and new-with-box condition. The trade-off is that the choice is tied to that men's US 10 sizing and multicolor presentation. At $140.00, it is also close to the upper end of the four-shoe price range.
Merrell Men's Agility Trail WATERPROOF Shoes Mariana NEW

Merrell Agility Trail is the practical weather-focused choice, with a waterproof upper and bootie waterproof construction. The description also names FloatPro foam, 3mm lugs, a bellows tongue, padded collar, TPU overlays, a removable EVA foam footbed, and FLEXconnect grooves. Those details make the shoe relevant for easy trail running, walking, and routes where keeping feet dry is a priority. The limitation is the specific configuration: a men's Mariana option with lace-up closure. It is marked new with box, and the $77.45 price places it at the low end of the comparison.
Final recommendation by use case
- Wet-weather running: Choose the Salomon if women's size 11 fits your needs and you want the technical-trail model; choose Merrell if the men's Mariana configuration is the right match.
- Ultra-distance focus: Fuga EX3 is the clearest choice for the long-distance off-road description in men's US 10. Adidas suits a men's size 9 shopper drawn to the Terrex Soulstride Ultra Trail name.
- Lowest price: Merrell is the starting point at $77.45. The difference between it and Salomon at $149.99 is $72.54, making the price spread meaningful without changing what either shoe is designed to emphasize.
- Boxed footwear: Salomon, Fuga, and Merrell are the options marked new with box; adidas is the choice marked new without box.
