The Fast-Trac Nitro 4 is PUMA's trail shoe for ground that fights back. NITROFOAM runs through the midsole at a 32 mm stack, and the PUMAGRIP ATR performance rubber outsole is, in PUMA's words, trail ready for traction on ice, mud and unstable surfaces, in a package of about 286 g.
It suits you for trail runs on soft or slippery ground, where grip underfoot counts for more than a big pillow of cushion, and for anyone who wants a dedicated trail shoe.
It is not a road shoe, and it is not a light one. The balanced stack gives up the plush feel of a max-cushion trail shoe, which you will notice over long hours.
