These are FESN soft wheels. They haven't been used much, so I haven't done any power slides or anything like that. I think there's hardly any wear and tear. W.P.S.I, the speed cruising gear brand launched by FESN. These high-rebound wheels use high-rebound urethane and a strong plastic core to enable high-speed rotation with soft wheels. The wheel contact surface is stone-ground, which improves sliding performance while maintaining the original gripping of soft wheels, resulting in soft slide urethane. 72mm square lip 72mm large diameter, 56mm contact surface area, the heaviest model currently produced in the WPSI wheel lineup. Similar to the 70mm, this is a high-speed rotation model with a large-diameter core. The initial speed is heavy, but once you get up to speed, you can ride with unwavering stability. It combines both the stickiness of carving and sliding, and is suitable for cruisers from mid-size to longboards.
