Their goal Nike Flyknit Air Max Womens cheap in the study, therefore, was to determine how women assigned to the three categories of footwear based on their observed degree of pronation would fare in terms of pain and injury experienced while training for a half marathon.

Interesting study and a great post about this important topic. Time and money are both precious ¨C so it is hard for the average runner to experiment¡­ more studies of this kind will be telling indeed.

Wondering also to what degree the level of cushioning and heel-to-toe ratio had to do with performance. I submit a flatter, firmer neutral shoe is more stable than a cushy, higher heeled neutral shoe.

A total of 105 women were classified as either neutral (51 women), pronated (36 women), or highly pronated (18 women). Now here¡¯s the really interesting part. In a shoe store, the neutral women would be assigned a neutral shoe, the pronated women a stability shoe, and the highly pronated women a motion control shoe ¨C go it? In the study, however, th Nike Free 3.0 Flyknit Mens cheap online e researchers took each of the three groups of women (neutral, pronated, and highly pronated), and subdivided them into sub-groups so that one-third would get a neutral shoe (Nike Pegasus), one third would get a stability shoe (Nike Structure Triax ¨C incidentally, the Triax was my first ¡°real¡± running shoe, assigned by one of those slow-motion eyeballs I mentioned earlier), and the final third would get a motion control shoe (Nike Nucleus). This was done for each of the pronation groupings, so that what we have here is some women in each pronation category wearing each type of shoe (i.e., many of them wearing the ¡°incorrect¡± shoe for their foot).

Lets take a look at some of the science. In this post I¡¯m going to focus on a study published on-line in June 2010 by Ryan et al. in the British Journal of Sports Medicine. One of the co-authors of this study, Gordon Valiant, works for the Nike Sports Research Laboratory ¨C he¡¯s the same biomechanist that Alberto Salazar and Dathan Ritzenhein worked with to modify Ritzenhein¡¯s footstrike from heel to midfoot. Keep this in mind as you read this ¨C one of the co-authors works for the biggest sports shoe manufacturer in the world. In their introduction Ryan et al. state the following surprising detail: ¡°¡­despite over 20 years of stability elements being incorporated in running footwear there is, as yet, no established clinically based evidence for their provision.¡± They then go on to point out that ¡°Motion control running footwear has yet t Nike Free 3.0 Flyknit Womens online sale o be proven to prevent running-related injuries.¡± Pretty amazing, isn¡¯t it? Makes one wonder if the shoe makers actually have ¡°proprietary data¡± supporting these designs, or if the whole pronation-control shoe paradigm is nothing more than a giant marketing gimmick.

I have to disagree here. By going to the running store they have stopped my jnjuries. Now I have very no or very little pain once I was fitted for right show with my step. I have talked to other people who have said the same thing. S Nike Free 6.0 Mens sale cheap o it not always the case of being fitted causes onjuries.
