Al's Sport Shop, founded in 1979 by the Treadwell family, is Santee's original team-outfitting headquarters on Mission Gorge Road, stocking game-day equipment from Adams USA, Wilson, Schutt, Rawlings, and Under Armour. The in-house embroidery and sublimation department produces custom team uniforms, signs, banners, and trophies — a print-and-stitch pipeline that parallels the signage production at Lasting Impressions Print Shop further east on Mission Gorge Road. Inventory spans baseball gloves, football helmets, soccer cleats, basketball shoes, and volleyball kneepads, covering youth-league through adult-recreation sizing across each sport. The store's equipment-fitting service measures players for helmet shell size, shoulder-pad arch width, and glove pocket depth before purchase, a personalized sizing protocol that serves the same fitness-minded community anchored by Chuze Fitness at Santee Town Center. Highest-complexity orders involve full-roster uniform packages — sublimated jerseys, matching shorts or pants, warm-up tops, and embroidered caps — produced on a four-to-six-week turnaround for league deadlines across East County San Diego.
