  • The outsole gets a serious makeover in the Lahar 6 GTX. Asics is now using lesser, but definitely more aggressive and bigger lugs. Consequently, runners will enjoy a more stable and firmer grip on a multitude of trail surfaces. The spacing of the lugs also helps in preventing mud from sticking in the outsole. A new crash pad in the outsole gives it much-needed flexibility and enhances the transition from landing to take off.
  • Comfort goes up a notch by virtue of more padding in the ankle and collar. This upgrade in the Asics trail running shoe padding should mean a more luxurious feel for everyday training.
  • The heel area utilizes a more structured heel cup. Asics wanted to provide runners with something that can really cradle in the heel in support and to limit the risk of heel slippage.

Runners will be very glad to know that Asics did not tamper with the fit and sizing of the past model. The Gel Lahar GTX 6 remains to be a shoe with medium heel and average midfoot while the toe box is slightly more generous than standard. This fit will be perfect for runners with standard widths or for those who love a spacious toe box. The regular widths of D and B for the men and women, respectively, are available. Sizing is standard with choices from 6 to 15 for the men’s and 4 to 12 for the women’s.

Just like the popular Asics GT 1000 7, the shoe's outsole is a combination of AHAR, which is a carbon rubber exclusively made by Asics for superior durability and Gum Rubber that is really something in providing gum-like stickiness on the trail. Complementing these two are sizeable and multi-directional lugs that provide great leverage and bite on uneven trail. A rock protection plate between the outsole and the midsole offers great protection from sharp objects.

Shock attenuation and cushioning are provided by the Gel Cushioning System in the Rearfoot and Forefoot. This is an award-winning silicon-based gel that mainly very popular because of the way it disperses shock upon impact. The Trusstic System, which is what Asics calls it thermal plastic unit in the midsole, makes the run more stable and adds torsional rigidity, which is very important on the uneven trail.

A mesh upper gives excellent shoe ventilation. Just beneath the last layer of the mesh is a waterproofing membrane called Gore-Tex that is really effective in keeping off water. Hot Melt Overlays provide support and structure in the midfoot. Running in low-visibility areas will be enhanced by the presence of 3M Reflective Materials. Preventing small rocks and trail debris is the specific purpose of the Anti-Gravel Tongue.
