It's worth noting that spiked shoes are generally more difficult to clean than spikeless shoes, due to grass and mud getting caught in the cleats.
Having said that, it’s nothing a simple scrub with warm water and a toothbrush won’t fix. Rather than banging your shoes together, which could damage the cleats, take a toothbrush to the cleats to seek out any dirt that’s lodged in the nooks and crannies on the sole.
Better still, some cleats are removable, simplifying the cleaning process even further. Once they’re clean, simply pop them back on and you’ll be good to go
