I bought these because my old ones were worn out. I have been buying the same New Balance MW847L for 8 years, two or three pair a year. This latest version 4 (or 3 ) is causing terrible foot cramps at night and ankle and shin pain. I don't know what they did to the foundation but is is causing me pain plus they upped the cost $25. And the laces are a sham, way too long and come undone all the time. User's recommendation: They are not the same as they used to be at a higher price!
