What about Selle An-Atomica LD, ED-S, and ED slot shapes?
• All three slots provide essential anatomic relief throughout the forward 70% of the slot. • The rear 30% of each cutout is specifically engineered to provide the best relief, support, & Flex-Fly motions to meet various conditions. • LD – the most supple slot for long distance relief and the most sensitive bottom. • ED-S – an intermediate slot design that provides relief and support for less sensitive bottoms. • ED – the firmest saddle slot design that provides excellent anatomic relief where it is needed most and a firm support structure for the least sensitive bottoms.
