The short answer: All skates sold at our store have a decent soulplate
The soulplate was developed mid 90's after the first grind was done. The first soulplates were just little blocks of plastic mounted underneath the existing recreational inline skates to enforce them. Since then a hardware revolution occured from the mid 90s to the mid 00s. In those 10 years it was established how a modern day soulplate should look like and it has not changed since
All soulplates that were developed after 2005ish are just very similar in dimensions so our advice is not to think to much about this when you buy your first pair of skates. There are way more important things to think about like the way the skate fits your foot or even wether you like the styling of the boot.
