Running shoes

Owners treat the Ghost 17 as a reliable, well-cushioned daily trainer that comfortably handles easy miles, long runs, and even half marathons. Most find it soft and supportive with a pleasant step-in feel, though several note it's on the heavier side and prefer something faster for racing. A few longtime Ghost fans feel the redesign changed the shoe and found the toe box narrower than expected.

Owners are split on the Speed 4, and the complaints cluster hard around fit. The most common gripe is a narrow, pointy toebox that cramps and rubs the pinky toe, with several runners reporting toe numbness or circulation issues a few kilometers in. A lot of people also feel the midsole is firmer and deader than expected, with some saying it rides like a heavier daily trainer than a snappy speed shoe and takes real work to lock down.

A durable, versatile daily trainer with a wide toe box and grippy outsole that fans love for runs, work, and all-day standing. A vocal minority find it stiff, firm, and brick-like, with some reporting arch or tendon pain.

Owners are split on the Endorphin Speed 5: many call it the most stable, versatile do-everything Speed yet, with an improved roomier upper and a smooth rocker that's happy across tempo, speed work, and many longer runs. Others feel it rides firmer and more muted than the 4 and earlier versions, having lost some of the bounce and punch. Durability is a recurring worry, with several runners reporting early outsole wear and the foam going flat sooner than expected, and a few find the $175 price hard to justify.

Owners love the Boston 12 as a fast, durable tempo and interval shoe that holds up for hundreds of kilometers, but the gripes are loud and consistent. The biggest complaints are a stiff, plasticky upper with terrible laces that won't stay tied, heel slip and a long fit that forces many to size down, and a firm ride that feels brick-hard until a long break-in. A number of runners also report forefoot blisters and ball-of-foot pain from the narrow, unforgiving upper.

Owners call the Boston 13 a genuinely versatile do-it-all trainer with a firm, stable ride and energy rods that make it snappy for tempo and faster work, backed by a much-improved upper and a tough, grippy outsole. The trade-off is comfort: many find it too firm once runs stretch past roughly 10 miles. Fit is the other catch, with a narrow tapered toe box, fussy laces that can bite or loosen, and a slippery stock insole several runners swap out.

Comfortable cushioning wins loyal fans, but a large share found the 16 runs narrow and tight in the forefoot, with awkward lacing and blisters driving returns and size changes.

Owners love how soft, bouncy, and comfortable the Novablast 5 feels fresh out of the box, and most call it a versatile daily trainer with a roomy toe box for the price. The big recurring gripe is durability: the midsole bounce dies early for many runners, often between 100 and 300km, after which it feels flat and lifeless. A sizable group also reports forefoot or arch pain they blame on the front pod, and several note slippery grip on wet pavement and a loud, slappy ride.

A light, well-cushioned daily trainer with a smooth rockered ride that runners find comfortable and reliable for easy miles. Some report the cushioning going flat after 100-150 miles and heel-collar rubbing.

Owners are genuinely split on the Ghost 18. Fans say it's a clear step up from the 17, with a roomier toebox, a more secure heel, and softer cushioning that holds up for long days on your feet. The recurring frustration is the heel collar digging into the ankle, an irritation that sizing up to wide or 2E doesn't fix and that sent several people back to the store, plus complaints that the ride feels firm and clunky. It tends to work best for those who want a roomy, everyday trainer and didn't have ankle trouble in past Ghosts; if you're sensitive around the ankle, try before you buy.

Owners who like the Clifton 10 praise its plush cushioning and smooth, all-day comfort for walking, standing, and easy runs, especially those with wider feet, and many call it the most cushioned Clifton yet. But sentiment skews critical: a large share say it triggers foot, heel, arch, knee, or Achilles pain, often blaming the raised drop and unstable soft foam, while the midsole goes dead around 300 miles and the outsole peels or falls apart well before it should. Many longtime fans feel it's a firmer, narrower, heavier step back from earlier Cliftons and no longer the value it once was.
