I'm on the fence about this. I think it would make your head too warm!

I had to contact We.Retail to obtain warranty information for a water bottle. I opted to email instead of call, and I still had the information I needed, in hand, less than 24 hours later. You can't ask for better customer service.

Felicia, unfortunately that will not work. Snorkeling fins are generally too narrow around the ball of your foot to allow for a bootie. It would be pretty uncomfortable if it were even possible, in my opinion.

One of my kids has a silicone allergy, so fortunately for you I have already done the research on this! If you are out there looking for snorkeling fins, you won't find much in the silicone free department. However, if you look around for SCUBA fins, you will find a pretty decent selection. The SCUBA fins will offer a heel strap that clicks to tighten, and is made entirely of plastic. The only drawback: you will need to wear neoprene dive boots. They are quite comfy and keep your feet warm, but it is another expense.

The M2121 pedals take a standard MTB cleat. Fortunately, you don't even have to worry about any of that. The pedals are actually packaged with the cleats! All you need to do is buy these pedals and then some MTB compatible shoes. Sometimes, the shoes will come with the cleats as well, depending on the brand. This is handy because you will wear the cleats out. I have the M2121 and this is a picture of my setup.

Aaron, thanks for the reply. I will definitely look into getting SCUBA fins. I've already accepted the fact that I will have to pay extra on a few things here and there because of my allergy, and this option doesn't sound unreasonable at all. I'm wondering if I can just buy the booties and wear them with silicone snorkeling fins since my skin wouldn't come in contact with the fins at all. Maybe that would save me some money_..

I would like to know the materials generally used in the snorkeling equipments. Unfortunately, I am allergic to silicone and need to make sure the strap around the neck won't be a problem for me.

I believe so, and it is using an amazing technology named AEM Communities behind the scene.
