2017 BOSTON WEEK: sold out shoes?

SPECIAL EDITION SHOES  2017 IS THE 29th year that adidas has been Exclusive Supplier of Officially Licensed Merchandise to the Boston Marathon. You can shop the goodies offered by this company through the B.A.A. website. Other sports apparel and shoe companies have joined the fun as well.
 
Competitor.com showcases 7 special-edition shoes for this race in a slideshow composed by Adam Elder with images by Olivia Baker. Only Adidas shoes and apparel can display the official race logo; there’s a label on the tongue of the “adidas adizero Adios 3.0” shoe that comes last in the article. I love the rear-view styling of this blue and yellow colored pair; the right foot has the distance “26.2”, and the left has ”BOS” on the heel (seen in the slideshow).
 
Below is a Runner’s World review of that shoe, which was given the “Best Update” Award by the magazine earlier in the year.
 
“It’s hard to improve upon the Adizero Adios 2, the shoe worn by the fastest marathoner ever, Dennis Kimetto, when he ran 2:02:57 at the Berlin Marathon in 2014. Testers confirmed, however, that this update of the popular racer is even better. The midsole remains consistent: A full-length slab of springy Boost foam is rimmed with firm foam around the top to add a bit of stability and create a fast-rolling feel. Adidas tweaked the outsole, wrapping the forefoot in a thin, waffle-cut layer of stretchy Continental* rubber, improving flexibility, traction, and durability. Testers also reported that the mesh and suede-like upper feels softer and fits larger feet than previous versions.”
 
* Earned Runs comment: this is material from tire manufacturer, Continental™.
 
In searching online for this shoe, (Boston adidas adizero Adios 3.0) I discovered it SOLD OUT very early on one site, Marathon Sports, possibly explaining why it was not to be found on the adidas site. 

Lesson learned for those who want uniquely styled footwear from any of the big city marathons in which special editions are promoted.  Search and buy early!!!  If you like the look others will too. Only limited supplies are usually made available. Likely the highest demand will be generated for officially licensed items.
 
In addition to adidas, the footwear shown in the Competitor.com piece comes from Nike, Brooks, Saucony, Sketchers, and Altra. Not part of the slideshow, ASICS has also gotten into special-shoe-for-Boston game with its DynaFlyte-Boston model.  
 
Is it appropriate to wear special edition shoes if you did not run in the race?  If you’re a great fan, it would seem permissible if an explanation was provided when the question about race participation arose.
 
RUN HAPPY!
