Final answer:
Soccer and cricket are two sports that do not require large fields and can be played by children in smaller spaces with minimal, improvised equipment.
Step-by-step explanation:
The two fields which do not explode beneath the feet of running children are soccer and cricket fields. Unlike equestrian sports that require vast amounts of space, soccer and cricket can be played in smaller areas and do not necessitate large, specialized fields. For children to engage in these sports, empty lots, streets, or small parks can suffice as playing fields. Simplified equipment such as homemade goals and balls can be used, which reduces the need for extensive resources or space.
