The Babolat Red Foam ball, made of foam, is therefore ideal for the first strokes with a racket. The Red Foam is larger, softer, and significantly slower than a conventional tennis ball. This gives tennis students time to practice their movements and accurately assess the balls. The Red Felt meets ITF requirements and the Play and Stay coaching concept (Stage 3). \u003c\/p\u003e\n\u003cp\u003eTake advantage of the Babolat Red Foam beginner ball and get a feel for the racket and ball!\u003c\/p\u003e\n\u003cp\u003eHighlights:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003ea soft beginner ball with 75% reduced speed\u003c\/li\u003e\n\n\u003cli\u003egood visibility\u003c\/li\u003e\n\n\u003cli\u003efast learning curve\u003c\/li\u003e\n\n\u003cli\u003esuitable for novices and children aged 3-8 years\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Babolat","offers":[{"title":"Default Title","offer_id":57410039775564,"sku":"TF10785","price":79.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/7830\/2796\/files\/babolat-red-foam-borsa-da-24-palline-516004_A.png?v=1786022384"},{"product_id":"yonex-muscle-power-20-kinderballe-60-stuck","title":"Yonex Muscle Power 20 Kids' Shuttlecocks 60 pcs","description":"\u003cpre id=\"tw-target-text\" class=\"tw-data-text tw-text-large XcVN5d tw-ta\" dir=\"ltr\" data-placeholder=\"Translation\"\u003e\u003cspan lang=\"en\"\u003eThe correct introduction to tennis for younger players is crucial.
