Pulsars spikes feel soft to the hand touch; for 210lb male that softness translates to a very cushion-like feeling on both grass and concrete, which could go both ways depending on what you like. Spikes elevate you ~0.5" off the ground but the grip on grass is superb, as it resists foot twisting even on moist ground. Some visible wear and flattening after wearing them for one round, but I expect them to settle in and grip even better once they flatten out a little more. For individuals that want cushion and comfort in their step, the pulsars are definitely recommended. Five Star!Note: for those that have older FastTwist shoes (mine are 2009 Oakleys) the locking mechanism in these FastTwist+ProLock spikes may not align exactly to your shoe. It will take more precision to get the threading aligned and more muscle to get them secured. They will eventually fit if you have the patience, but just takes more finesse.
