Designed specifically to fit a woman's feet, the Merrell Siren Sport is lightweight, comfortable and grippy, reviewers say. Early feedback for the newest version, the Siren Sport 2, is similar. Two widths accommodate most foot types, and these stable hiking shoes have a decent record of durability for such light footwear.
No break-in period. Like its predecessor, the Merrell Siren Sport 2 comes in both normal and wide widths. Yet some shoppers seem unaware of this, and complain that the normal width is too narrow in the toebox. These shoes are known to run about a half-size small, but once users get into the proper size and width they're happy with the fit. Like the original Siren Sport, the Siren Sport 2 is comfortable and supportive right out of the box, they say.
A Merrell.com poster who has flat feet and overpronates -- her ankles roll in -- writes that these shoes are a "foot saver," while a Moosejaw.com user says, "I'm crazy about Merrell shoes and their foot beds made specifically for women. This shoe is light and flexible and overall an amazing choice."
The Siren Sport 2 readily accepts orthotics or aftermarket insoles, so if you agree with the few owners who say it's not cushioned enough, you can simply add your own. Omni-Fit quicklaces make it easy to get in and out of the shoes, although a couple of users warn that they occasionally need to be re-tightened. The new version weighs 1 pound, 7 ounces, about 2 ounces more than the original.
Stable and supportive for a light hiker. Both the Siren Sport 2 and the original Siren Sport get better-than-average reviews for traction on all surfaces, even slick mud. "They have awesome grip in extremely muddy conditions," says one REI.com user who took her Siren Sports hiking in the Nicaraguan rainforest. "Grips the granite wonderfully, provides cushioning on the approach and looks great, too!" posts another.
A few owners are fans of the Siren Sport's relatively stable ride, and blend of protection and flexibility. "The sole is just-right stiff, it's not going to go limp on you at the peak of the trail, but it doesn't feel like walking on boards. The tread is fantastic, very grippy and wonderful," reports a hiker at Moosejaw.com.
Because it's made of mesh, the Siren Sport 2 isn't waterproof but dries out relatively quickly. It's also available in a waterproof version (*MSRP $100).
Good for a light shoe. Lightweight mesh shoes aren't known for their durability, but the Merrell Siren Sport seems to hold its own. The Siren Sport 2 hasn't been available long enough to establish its own record, but it's similar enough to the original that we can extrapolate from that. Although we found a smattering of durability concerns, they're usually accompanied by the admission that the shoes were put to rough use.
As long as you don't tear the uppers on brush or other debris, the Siren Sport holds up for at least a few years of near-constant use, which is a good track record for such a light shoe. "Wore out the first pair after a couple years of daily use," says one REI.com reviewer; another posts that she has used her Siren Sports frequently for more than a year and "hardly any of the traction is worn."
Review Credibility: Good The original Siren Sport was a popular shoe at Amazon.com, receiving 4.7 stars out of 5 after more than 130 user reviews. The updated Merrell Siren Sport 2 is off to a good start as well, with an average rating of 4.6 stars out of 5 after about 20 posts.

Review Credibility: Good We're always careful about using reviews from manufacturer websites, but this rating of 4.1 stars out of 5 from about 15 users makes it clear that Merrell isn't censoring comments on the Siren Sport 2. Most owners say the regular-width shoe is comfortable but a little narrow; there's a wide width they could size up to. The narrowness is the biggest complaint here and seems to explain the low rating.

Review Credibility: Good The Merrell Siren Sport 2 is sold at REI.com but hasn't accrued any user reviews yet; about 75 women give the original version an average rating of 4.3 stars out of 5. Most like its lightweight comfort, good cushioning and great traction, but a few wish it were water-resistant and say it doesn't offer enough support and stability.
