Today we're taking a look at two new shoes from Altra. Both of these shoes follow the same fit philosophy as the rest of the Altra line. This means they're going to have a wide, foot-shaped toe box, and feature zero drop from front to back. As you can probably guess, this means they'll feel very similar to the other kicks we've previously reviewed from Altra Zero Drop lineup. What's special about the shoes at hand is how far Altra has gone to cater to the triathlete. First up is the 3-Sum, a purebred, triathlon-specific shoe. Then we'll look at the Torin, a more traditional shoe that nevertheless offers a great training or racing option for triathletes. Click through to the full article for all the details.

  • The Altra 3-Sum proves that the zero drop experts are still on fire when it comes to great design.
  • The tri-specific 3-Sum has a one-piece construction that makes it great for a quick slip on during transition.
  • These holes are water ports, meant to help your foot wick away moisture or water.
  • Viewed from the top, it's easy to see the wide toe box, which Altra calls 'foot-shaped' because it lets your toes splay naturally on landing.
  • The interior of the 3-Sum is smooth all over, and lined with anti-microbial coatings to help fight odor. Both make it great for running sockless.
  • The 3-Sum is low stack and ultra light. This makes for a great ride, but my only concern is whether that also makes it susceptible to early wear.
  • The large built-in pull tabs are awesome, and make it really easy to put the 3-Sum on in transition.
  • The Torin is Altra's latest neutral trainer.
  • From the upper to the outsole, the Torin's design and construction represent the evolution of refinement that continues to make Altra a great brand.
  • The new tread pattern on the Torin is quite a bit different from that of the original Instinct.
  • Pull loops on the heel and tongue could be great for those running elastic laces.
