Who should NOT buy it

If you're looking for a more forgiving ride on hard-packed terrains, get the Saucony Peregrine 12 instead of the ST version. And if you don't want any compromise on traction, the OG Peregrine 12 also sheds off mud better.

For wide-footed runners, your toes will be happier in the roomy Saucony Mad River TR 2.

  • The upper is now made from recycled materials to limit waste and has a more enclosed mesh design to keep the mud out.
  • For better protection, a new rock plate and a more padded insole are added. 
  • It has less weight, trimming it down to 289 grams/10.2 ounces in US M 9 from 326 grams/11.5 ounces.

Chart-topping grip

"If someone told me they were this mud-grippy and fast I wouldn't believe them, but believe me they are." This is from an expert who talked about the shoe's grip. 

The Saucony Peregrine 12 ST is said to be a "mud monster" that in the deep mud grips "even to the point of surprise." The best summary from testing the shoe in the mud was: "the Peregrine excels where others slide."

Where it shows limitations is on wet concrete and wood. On these surfaces, it feels slippery. 

Outsole doesn't shed off the mud

After running on mud with "a lot of silt and sand," Saucony fans claim that the outsole doesn't get rid of the mud quite as well as they would have hoped for.

The Saucony Peregrine 12 ST mutes out the impact

There's enough cushion underfoot; you "don't feel every pebble" that can "punch against the foot." However, it feels rather harsh on hard dirt as there's too much impact; there are some reports of the feet becoming quite sore.

Ready for the long haul 

50 KM in, and there are still NO indications of anything wearing early, stated various testers. 

Supportive throughout

From the upper to the midsole, the Peregrine 12 ST keeps the foot stable. Those with normal to narrow feet agree to this, saying their feet don't slip in this shoe at all because it "feels more like a perfectly fitting glove than a shoe." And when "rocking side to side, the shoes barely move at all."

Those with plantar fasciitis, meanwhile, state that although this is a neutral shoe, the Peregrine 12 ST is very supportive underfoot. So much so that they can wear it all day.

Wide-footed runners, beware

Trail runners advise those with broad feet to look elsewhere. The Saucony Peregrine ST is "much too hard to get on;" they had to use a shoe horn. Even more, the toe box is not that spacious.

Lacing has never been this quick
