Do synthetic foam mousepad bases last longer than natural rubber ones?

Yes, synthetic foam bases (neoprene, EVA, or closed-cell blends) are typically more durable than natural rubber. Natural rubber can dry out, crack, or lose grip over time, especially in heat, humidity, or sunlight, and may develop a crunchy edge. Synthetic foam stays flexible, maintains shape, and resists sweat and UV damage. For durability only, go synthetic.
