2011 Newton Gravitas = Gravity
Neutral Distance Trainer
As for the general construction, the Newton Gravitas upper shoe material consists
of a larger mesh than most other trainers. Unlike other trainers that contain leather
or other synthetic non-breathable material, the Gravitas is almost entirely covered
in different size mesh. The mesh not only provides more air conditioning (my feet
were almost dry after long runs), but it also lends to the flexibility of the shoe.
The difference is quite notable as compared to the Asics Gel Nimbus 12 & 14 and
Cumulus 13, which are all fairly stiff shoes. Having more room in the toe box takes
some getting used to and could be interpreted as a lack of support. However, after
40 miles of testing and suffering no repercussions, it is apparent that the support is
more than adequate.
One of the most obvious features of the Newton running shoe are the
rubber ‘runners’ under the forefoot. The extra rubber on the sole of the Newtons
really makes a difference on pavement. Not as noticeable on trails or rocky scree.
The responsiveness is hugely beneficial. Compared to the Nike Shox , the extra
cushioning makes more sense in the forefoot than in the heel, for two reasons: 1)
The extra push, or bounce, provides for a better, more efficient stride, and 2) there
is less opportunity to roll the heel/ankle twist. The encouragement of a higher leg
lift because of the extra rubber cushioning, contributes to more knee bending and
kick, which is a huge benefit. This is probably more noticeable in long training runs
rather than sprints.
The lower impact on the leg due to the extra rubber cushioning is also quite
noticeable descending hills when it is important to get the most of your speed and
let go of the breaks, so to speak. Conversely, the push-back caused by the rubber
cushioning propels the body forward when using the forefoot to ascend hills.
The second most obvious feature of the Newtons is the reduced heel material. With
the lack of a ‘lip’ at the edge of the heel, a natural rocking motion is encouraged in
the stride. Again, less work is needed to move forward. Additionally, having a lower
heel eliminates the risk of twisting an ankle on trails or uneven ground.
Summary: I never thought I would run in neon orange with green detailed trainers
and now, I LOVE them. I ran more miles this week than I usually have and I do not
have any of the leg fatigue that I am used to. In fact, I feel like I could keep running
but am forcing a day off only because I know I should after 6 days straight.
