    They don't breathe enough,there's not enough ventilation getting through… the tongue flops all over, it's way too thin, and I'm busting through the sides of it.

    The Piranha is an ultralight shoe that provides a reasonable level of cushioning for its weight.

  • The Piranha 5 unveils several changes that should make it even better than before. As with almost every release of this line, the upper gets a slight revamp. Gone are the synthetic overlays, except in the forefoot. The upper is a near seamless one with printed overlays. This modification allows the upper to really mold to the runner’s foot. Since this is an almost seamless upper, it greatly reduces the risk of hot spots or irritation in the interior.
  • Fans of the Piranha series will notice that the heel is very flexible this time around. Only a small tab sitting on top of the sole holds the heel in place. This is a change that should delight most minimalist runners.
  • Lastly, the outsole gets a thorough makeover. There are presently hard and plastic lugs as opposed to pure rubber in the previous version. It does not make the Asics Piranha 5 a trail shoe, but the lugs make running on asphalt enjoyable.

The fit and sizing of the 5th installment of the Piranha are regular. As with most pure flats, this has a snug fit from the heel to the forefoot. The toe box offers just enough room for the toes to splay. Runners with average or narrow foot should be able to get the most out of this fit. Available widths are D and B while sizes are from 6 to 15 for the men’s and 5 to 12 for the women’s.


Asics’ proprietary DuoSole is an extremely light rubber with adequate durability. It is one of the biggest reasons why the Piranha 5 is an ultra-light shoe. There are numerous hard, plastic lugs in the forefoot for added bite on different surfaces. In comparison, the Saucony Kinvara 10 makes use of a modified ethylene-vinyl acetate (EVA) in its outsole.


The very popular Solyte midsole is the main component in this area. This is slightly firmer than some of Asics’ foams, which makes it an ideal platform for faster and more powerful takeoffs.


The upper is also ultralight and breathable. There are printed overlays for lightweight support. An industrial-grade sockliner provides enhanced comfort in the shoe.
