After surviving a hectic spring schedule that included 2 marathons and 2 half marathons, I am glad to be running shorter distances. Thankfully the only race I have on the schedule for the summer is the Peachtree Road Race, a 10k. While I am not officially planning to start training for the Chicago marathon until August 1, I am doing a 90 challenge to work on my nutrition and pace for the race. For each week of the 90 day challenge, I have specific goals to work on to help me in my pursuit of 4:30 finish time for Chicago. To kick off my 90 challenge, I tested Adidas UltraBOOST X (https://www.dickssportinggoods.com/p/adidas-womens-ultra-boost-x-running-shoes-17adiwltrbstxblkbrnn/17adiwltrbstxblkbrnn) shoes for the first 3 weeks. The UltraBOOST X model is a neutral shoe that designed to respond to your foot's movement through every stride to deliver maximum energy in return. So what is my experience?
The Shoe Design
While I rarely test shoes, I am always searching for new products to up my run game. I normally wear Brooks and Mizuno shoes because they support my flat feet. Straight out the box, the first thing I noticed about the Adidas UltraBOOST X shoes was the unique design. The shoe has a stretchy sock-like foot body for your feet. Initially I wasn't sure if I was suppose to wear socks with the shoes (I did).
The foot holder is separated from the sole at the arch. When I first put the shoe on, it felt like my foot was in a hammock. Once I walked around my foot felt normal and I didn't notice the separation that I mentioned earlier. There are plastic components: two on each shoe for the ankle/heel and for the Adidas signature design on the side of the foot. The shoe is light and toe box width was fine.
I started my 90 day challenge by attempting to run 2 miles at a sub 11 minute/mile pace in the shoes. Since I am flat footed, I normally wear a hard orthopedic insert in my shoes. I didn't wear the insert in the Adidas UltraBOOST X because it wouldn't fit. For the run, my feet felt uncomfortable for the first half mile. They felt like my feet do when I don't have adequate arch support. After a while my foot acclimated to the shoe. I also met my pace goal for my first run with them.
I ran with the shoes for a few 5ks and for a 10 mile long run. For all the runs, I had the same experience with beginning of the run have uncomfortable feeling in my foot and then eventually my foot acclimated to the shoe and run was fine.
While I think the Adidas UltraBOOST X has a great design I don't think it is the shoe for my Chicago Marathon training. The inability to use my orthopedic insert limits my runs to shorter distances. I do plan to wear them distances up to 10k. I will say that it is one of the most interesting pair of shoes I have tried based on its design alone.
