Thanks for all the extra info. I like to learn about the things I use, especially something I love as much as Force Fins. Force Fins kept me in the water. I broke/sprained both ankles playing football from chop blocks, which are illegal now. Imagine a 300lb player hitting you in the ankle 40 times/game-you get your ankles hurt at least once per season. Normal fins hurt my big feet and broken ankles. I was going to give up on diving and snorkeling even though I had a reef behind my house. Then I saw the add for Force Fins-as soon as I saw the picture I knew they would work. Maybe it was the kinesiology classes I took but they looked right. So I got a pair, went out to the beach and not only were they super comfortable but I realized I was moving at a good pace. 30 plus years later and I'm still thankful I'm in the water. During the last 8 months of Covid lockdown, I've only missed about 10 days of swimming laps with my force fins. No ankle/foot pain at all. Can't wait to get the hockey fins and zip through the water. I'm glad to know they will be easier to bend and snap than my extra's.
