RockCreek.com offered the Teva Sling King in my size (mens 8 USA size) for only $25 so, I thought they'd be worth trying. The first problem I noticed is that the length in front of the big toe is way too short for my foot. This is odd because my Teva Spitfire sandals are also size 8 and fit me a lot better. I think this Sling King might suitably fit someone who wears USA mens size 7, The second problem, I was disappointed with how stiff the sole is in the forefoot area. I have 3 examples of cheaper water shoes and each of them offer a heck of a lot more ground-feel than the Sling Kings do. I think this is partly due to the rubber compound and partly due to the Tevas having a toe spring. I didn't expect these to be great but hoped that they'd at least fit well and be flexible enough. I'm going to either give these to my mom or send them back for a refund.
