So in trying to choose the appropriate shoe for my marathon this weekend - yes, I literally still don't know what shoe I'm going to wear - I decided to throw all of my current shoes on a scale, just to see how they stacked up. Not surprisingly, the minimalist shoes were much lighter than their thick-heeled counterparts. Typically I wear a size 12.5 for running, and I've found that those are about an ounce heavier than the published shoe weights, which are usually based off of a size 9 for most manufacturers. For example, my Brooks Pure Flows are sold with a published weight of 8.8oz, and as you can see above, my size 12's without a supplemental insert tips the scale at 9.7oz, which is obviously to be expected with more material in the shoe.
|Top left - Brooks Adrenaline GTS ... 13.1oz, Top right - Brooks Ghost Trail with supplemental insert ... 15.6oz, Bottom - Brooks Glycerin with supplemental insert ... 15.7oz|
For this race, as with the past couple, I'll most likely use the size 12 Brooks Pure Flows. They're fairly light weight and seem to handle 26 miles fairly well. I'm not in love with them, but they seem to be the best alternative I've found. I used to run in the thick-heeled shoes for a marathon, but sweat-soaked trail-type shoes become very heavy to lift in the late stages of a race. With the lighter shoes, I never really notice the weight, but after about 22 miles, I seem to become aware of the pounding on the soles of my feet. But I would rather sacrifice a little comfort, as opposed to carrying extra weight at the end of my ankles.
So anyway, there's my little shoe study. Fascinating, I know. Yes, I am a nerd. But hopefully choosing the right shoe will help get me to the finish line a little quicker. I'm gonna need all the help I can get. Have a great day!
... be great today!
