Choosing between trail running shoes can be difficult when one is named for an ultra-trail use case and the other provides more explicitly described trail features. The Adidas Terrex Soulstride Ultra and Merrell Agility Trail point in different directions, so the useful shortcut is to decide whether exact model identity or a detailed construction profile matters more.
Quick verdict
Adidas is the natural match for shoppers specifically seeking the Terrex Soulstride Ultra name, a black color, and a men's size 9. Merrell is the clearer pick for someone who wants a lower listed price and more detailed trail-oriented construction information. Both are lace-up men's shoes, so closure does not separate them.

Where each product wins
Adidas: the model-specific choice
Adidas wins when the shopping goal starts with a precise model phrase. The title identifies the Terrex Soulstride Ultra Trail Running Shoes IE8453, while the attributes specify black, men's, size 9, and activewear. That combination creates a clear match for someone whose preferred shoe is already narrowed to those details. The trade-off is the stated new-without-box condition, which makes packaging an important part of the decision.
Merrell: the price-and-detail choice
Merrell wins on the listed price, with a $16.55 spread between it and the Adidas shoe. It also gives shoppers more construction details to weigh, including FloatPro foam, 3mm lugs, breathable mesh, synthetic and TPU components, and FLEXconnect dual-directional flex-grooves. Those details make the Agility Trail easier to assess by feature rather than by model name alone.
Product notes
Adidas Terrex Soulstride Ultra Trail Running Shoes
The Adidas entry suits a shopper who has a firm target in mind: the Terrex Soulstride Ultra model in black and men's size 9. Its product identity is unusually specific, including the IE8453 code and adidas TERREX product line, so it is easy to distinguish from a general trail-shoe search. The practical limitation is the stated new-without-box condition; original-box packaging is not part of the described purchase. This shoe also carries the higher listed price, so the exact model, color, and size should be the reason to choose it rather than simply its lace-up format. For a shopper already looking for that named Adidas shoe, the specificity is the main appeal.
Merrell Agility Trail Waterproof Shoes
Merrell makes the more equipment-defined case. Its description names FloatPro foam, 3mm lugs, breathable mesh, synthetic and TPU upper materials, and FLEXconnect dual-directional flex-grooves. That gives shoppers several concrete attributes to prioritize beyond the Agility Trail name. The limitation is its stated use-case language: the shoe is framed for easy trail running. Someone specifically shopping for footwear labeled Ultra Trail may prefer the Adidas title instead. Merrell is therefore a sensible fit for buyers who want the detailed Agility Trail setup and can work within that easy-trail positioning.
Final choice by use case
- For wet-weather protection: Choose Merrell, because its comparison details specifically identify a waterproof upper and bootie waterproof construction.
- For an exact model-led purchase: Choose Adidas when the Terrex Soulstride Ultra name, black color, and men's size 9 align with what you want.
- For the lower listed price: Choose Merrell; the $16.55 price spread is concrete, while both shoes use a lace-up closure.
The bottom line is straightforward: Merrell is the better fit for a weather-focused, feature-defined purchase, while Adidas is the better match for shoppers committed to a specific ultra-trail model identity.
