Yes, the men's Nike Zoom Superfly R4 spike can be used on grass. The compression pins would most likely be best for the 'cork' type tracks though...any surface with a bit of a rebound. For natural type surfaces such as grass, you may want a 'needle' type of pin instead...sku #73871, or a 'pyramid' design...sku #71291, or some may even use the longer 'javelin' type of pins...sku #37199. The Sprint spikes can be used for jumping events if you so choose. It comes down to personal preference. Keep in mind though that jump spikes are designed and tested for jump events and would probably help better your performance.
