Being an avid distance runner, I spend alot of time looking into my next running shoes. The MR790s have a light heel, good if you tend to run with more mid foot impact, terrible if you are a heel toe runner, and are very light but versatile, with decent grips. Good news for those with quick feet, bad news for those that work the life out of shoes. (After a week from my purchase, the grips were already worn away. I predict two more weeks of intense running, and they'll be smooth.) The insoles that comes with the shoes are garbage, so if you are interested in these shoes for heavy usage, consider getting a sports insole. A good pair comes around $20. I used these shoes to run on asphalt, and I enjoyed them for jogging, but as for wide legged running, they hurt my soles. (Even with the new sport insoles, the shoes provides little to no comfort for heavy impact on the sole.) However, they are amazing for jogging, giving a smooth ride, and for cross training, they are equally as great, provide the same balance you would expect as being barefooted. The shoe comforms to your foot's motion, and cushions light, quick impacts that gives it a smooth feel. A downside is that the MR790's ankle collars don't grab the heel very tightly, almost giving the feeling your foot could slide out very easily, so expect to tie your laces tightly. Socks are a needed or your feet will burn from the imprint of the uppers. The design is very sleek, but provides little vehntilation for the foot. A few minutes into intense activity and your feet will be burning. The shoe is good for those who take it easy and do not demand alot out of their sport shoes, but for those who are very active and rely on shoes to be dependable, this is not the shoe for you.
