Those look like legit shoes. However, they are Barricade Court shoes, which are a lower quality i believe. You want ones called Barricade or ones called Barricade Boost. Barricade "Club" is another that has "Barricade" in the name but is not the highest quality.
Adidas started diluting their brand for some dumb reason by creating other, lower-quality shoes with "Barricade" in the name a couple years ago. Used to, there was only "Barricade" and nothing else.
Brand new Barricades for the current season will run about $150 IIRC (haven't played much tennis recently and haven't bought a pair recently for that reason). However, Adidas releases several styles per year, so often one from just three months ago will drop in price, and will keep dropping in price.
For example, here's Adidas Barricades from last year: https://www.amazon.com/adidas-Barricade-Tennis-Equipment-Yellow/dp/B01NBK7KLT/ref=sr_1_2?s=apparel&ie=UTF8&qid=1514010145&sr=1-2&nodeID=7141123011&psd=1&keywords=adidas+barricade Some are as low as $90.
Here's some 2016 models that might be even cheaper: https://www.amazon.com/adidas-Barricade-Tennis-Collegiate-Silver/dp/B019EKUZBK/ref=sr_1_7?s=apparel&ie=UTF8&qid=1514010226&sr=1-7&nodeID=7141123011&psd=1&keywords=adidas+barricade
Here are the strict Barricades that Tennis Warehouse has in stock right now: http://www.tennis-warehouse.com/adidas_Barricade_2017_Mens_Tennis_Shoes/catpage-MSADIB2017.html
Note all the colors. And they're all 2017 models. They used to carry older models. Maybe they've started stocking fewer or letting them go at lower prices faster.
I got my last pair on Amazon. I think I bought in early 2017 and it was a 2015 special model. https://www.ebay.com/i/222735632952?rt=nc&var=521592230391 <-- the ones I have now, but they're worn out so I really need to buy new ones, but tennis season is over until like March or April up here
