{"product_id":"adidas-ubersonic-tennis-shoes-kids-ih8171-1","title":"Adidas Ubersonic Junior Tennis Shoes - Yellow","description":"\u003cp\u003eThe adidas Ubersonic is the lightest, lowest shoe in adidas’s tennis range, and this is the junior version in yellow. It is built around speed — a light chassis, a close-to-the-court profile and a lace fit that locks the foot down — for young players whose game is starting to depend on how quickly they can get to the ball.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight build\u003c\/strong\u003e — Less weight to move means faster first steps and quicker recovery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-profile chassis\u003c\/strong\u003e — Keeps the foot close to the court for better stability through direction changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreathable upper with supportive overlays\u003c\/strong\u003e — Ventilated where it can be, reinforced where the foot pushes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLace closure\u003c\/strong\u003e — A properly adjustable lockdown that holds through hard lateral movement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable court outsole\u003c\/strong\u003e — Grip and wear resistance on hard and indoor courts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePadded tongue and collar\u003c\/strong\u003e — Comfort around the ankle over long practice sessions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance Overview\u003c\/h2\u003e\n\u003cp\u003eThe Ubersonic exists because tennis is won and lost in the first two steps. Stripping weight out of a court shoe makes those steps quicker, and sitting the foot lower to the ground makes them more stable — you feel the court rather than balancing on top of a thick midsole. For a junior who is beginning to move properly, that combination matters more than extra cushioning.\u003c\/p\u003e\n\u003cp\u003eWhere the shoe does add material is where the foot loads. Overlays reinforce the medial side that takes the push on a wide forehand, the lace closure gives a fit that can actually be tightened down, and the outsole is a tennis compound rather than a general trainer sole. The trade-off is honest: this is a speed shoe, so it is less padded and less forgiving than a heavier stability model, and it suits an active mover rather than a heavy dragger.\u003c\/p\u003e\n\u003ch2\u003eBenefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eQuicker first step and recovery from a genuinely light shoe.\u003c\/li\u003e\n\u003cli\u003eLow profile gives better court feel and stability in the corners.\u003c\/li\u003e\n\u003cli\u003eSecure lace lockdown for hard lateral movement.\u003c\/li\u003e\n\u003cli\u003eDurable outsole suited to hard and indoor courts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAdidas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eUbersonic Junior\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Code\u003c\/td\u003e\n\u003ctd\u003eIH8171\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColourway\u003c\/td\u003e\n\u003ctd\u003eYellow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAge Group\u003c\/td\u003e\n\u003ctd\u003eJunior \/ Kids\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClosure\u003c\/td\u003e\n\u003ctd\u003eLace-up\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface\u003c\/td\u003e\n\u003ctd\u003eHard and indoor courts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTennis shoes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhy Buy from YC Sports?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e✅ 100% Genuine \u0026amp; Authorised Products\u003c\/li\u003e\n\u003cli\u003e🎾 Tennis \u0026amp; Racket Sports Specialist\u003c\/li\u003e\n\u003cli\u003e📦 Secure Packaging \u0026amp; Fast Processing\u003c\/li\u003e\n\u003cli\u003e🤝 Reliable Customer Support\u003c\/li\u003e\n\u003cli\u003e🆕 Access to Latest Releases \u0026amp; Collections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFinal Verdict\u003c\/h2\u003e\n\u003cp\u003eThe speed option in adidas’s junior tennis range.
