What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Exceptional grip from well-spaced, multi-directional lugs that hold on wet, muddy, and technical terrain without notable wear
- Balanced DNA Loft V2 cushioning offers protection and shock absorption, especially at the heel, without feeling dead underfoot
- Secure, comfortable fit with a roomy toe box, padded heel counter, and strong heel lock — no break-in period needed
Reviewers push back
- On the heavier side for a trail running shoe, making it less appealing for tempo efforts or fast racing
- Reduced trail feel underfoot due to the generous cushioning stack and rock plate
- Mesh and soft rubber surround show wear faster than the more durable outsole and lugs
Reviewers broadly agree the Cascadia 18 is a reliable, well-cushioned all-terrain trail shoe that excels at versatility and comfort, with weight and reduced trail feel as its main trade-offs.
Reviewers praise
- Matrix woven upper combines durability, breathability, and abrasion resistance — addressing blowout weaknesses of the prior model
- Virtually no break-in period; fits comfortably and securely from the first wear
- Gore-Tex waterproofing performs well even in submersion and prolonged wet conditions without cooking feet in heat
Reviewers push back
- Heavier than the previous model — the durability upgrade comes with a measurable weight increase
- Traction becomes sketchy on slick or wet rocks, particularly after crossing water onto dry stone
- Side protection has soft spots; sharp lateral objects can still penetrate the upper material
“It literally feels like I've got a pair of running shoes on right now cuz they're so lightweight.”
Where reviewers split on Cascadia 18 GTX: Two reviewers felt the shoe seemed softer than its predecessor, attributing it to foam changes; Brooks and one reviewer maintain the midsole foam is unchanged and the softer sensation comes purely from upper geometry updates On X Ultra 5 GTX: One reviewer found the wider toe box an unqualified improvement; another noted it may require tighter lacing for narrower feet to feel locked in
