How can I detect if my running shoes are gone?

I am running with some NB 857 shoes, I id not count the amount of miles I run on it, is there a way I can find out if I need to change them like checking the cushioning, the in sole etc?

How can I detect if my running shoes are gone?
I think what you mean is, when is it time to replace your running shoe?





If thats the case check the tread, if its worn down to an unrecognizable point, def time to get a new pair of shoes.





As far as what to buy, this is an area you dont want to skimp out on. Your feet are the only part of your body that make contact with the ground when your running. So all the weight of your body is going on that small surface area. Shockwaves get sent up your leg and can be very painfull if you dont have proper support. Get a shoe that cradles the ankle, has a good tread, and possibly reduces the amount of shock that gets sent into your body.
Reply:look at your feet. no shoes? their gone.
Reply:Im guessing if you cant find your shoes for about a week or so then they are deffinately gone!
Reply:If your shoes are pretty flexible then that means it may be time to get a new pair. Ex: If you take your shoe in your two hands and its very easy to bend the toe to the heel= time to go. Also if you have been running with these shoes 5 to 6 days a week for the past 3 and half months, more than 5 miles each day, time to go. If the tread on the bottom of the shoe is worn and smooth, time to go.
Reply:I disagree with everyone else.





Any shoe, especially running shoes, is designed to last about 300-500 miles.





Running shoes are even more important. Since running shoes are designed to help shock absorb during the running, it is even more crucial for you to know your milage. A pair of shoe with bad shock absorption will increase your risk of injury such as plantar fasciitis, heel spur, shin splint, ITB injury, knee injury, etc. Even a properly fitted and relatively new shoe can cause those, but an old pair really put the risk high.





I usually change shoes every 400 miles and make an afford to estimate or track the number of miles. In general, I train about 20 miles a week, so I change my shoe every 4-5 months. That is a good estimate. When I look at those shoes that are replaced, everything look fine. I can't tell from the tread, the sole, the cushion, or anything - and that is the way it should be. If I were to change shoes when the cushion or soles are breaking down, I might already be injured.





If you want to run, change shoes regularly. Make an afford to track the milage and get rid of any pair more than 500 miles. Believe me, having run so many marathons and still having relatively healthy feet and legs (but also had my share of injuries, a few of them stemed from bad shoes), I know. It is not worth the money that you are trying to save.
Reply:Look at the shoes. Set them on a table and look at them from behind. How do they set on the table. Is there wear so that they are not setting correctly? How do they feel to your hands? You can tell if they have lost their cushion. Miles are just a guide they will not tell you when the shoe is good or bad. You can hold the shoe and fold its toe toward the heel,how much does it flex? Feel of a new pair and compare them.
Reply:Look at the sides of the soles in the area of the heel just behind the arch or medial post. If you see wrinkles in the rubber the cushioning is toast.





Manufacturers generally recommend replacing your shoes at 400-500 miles, but that could be less depending on your weight and what kind of surfaces you run on.
Reply:if tread is unrecognizable or flat then you need new shoes. most importantly if the sole of the shoe begins to wrinkle on the sides or you feel a lot of pounding in the heel from the pavement then its time to replace shoes.

How do they feel when you run? Do your feet feel like there striking the pavement due to lack of support/cushioning? Go to a running store for the best advice, most workers at exclusively running stores are knowledgeable in the sport. Especially in the shoe department, that's their job!
