There are probably as many variations of delivery technique as there are curlers. Each has developed their own delivery that balances comfort and performance. So you should take a close look at your delivery to see if the shoes you have your eye on are compatible with your delivery.
For example, a flat foot slide might want a shoe with a more rigid mid-sole that doesn’t have much flex, whereas a tuck delivery might benefit from the ability to flex or twist laterally.
Perhaps your mostly flat foot, but get up on your toe just enough that your heel is off the ice. Maybe a shoe that has a slight heel lift fits this better to keep the heel in contact with the ice?
Finally, how much does your ankle flex? Those high tops look super nice, but will they interfere with your delivery? Take a minute to examine how your slide and shoe interact before your final shoe decision.
