Running Shoe Update

 Here are my Adidas Supernova shoes with the Boost expanded thermoplastic urethane ETPU soles. These soles have great resilience or energy return so they are fun to run in. They weight 334 g per shoe which is 35 g or 10% more than my first generation Adidas Boost Shoes

I had worn these for about six weeks and you can see the discoloration of the ETPU from the sunlight.

The toebox on the new shoe is larger, and the shoe is more comfortable than my older Boost shoe.

I had a chance to visit Brooks in Portland and get a tour. I saw the treadmill lab where they test out the new shoes.

While I was there I got a discount a new pair of Ghost 8's. These are a similar design to the Ghost 6 & 7.

Notice that they went back to the black outsole. I wonder if that is for performance or for style.

This pair of Ghosts is the least homely pair. My Brook's shoes have been great to wear, but they are not so stylish.

These shoes are 345g. 10 g heavier per shoe than the Boost. 24 g heavier than the Ghost 7 and about the same as the Ghost 6.
