That sounds like about a size 3 youth size, maybe 3.5. XXS is for kids size 3-4, so it should work. I bought a size larger than I needed and it is way wide, but is excellent with fin socks. Fin socks make them more comfortable.

I'm not sure I'm right person to ask this as my size would be 47-48 cm. Also, there was no mention of age so the growth rate should be a consideration in making the choice. For me these fins were "too small" so go with the next size up from what you would purchase in a "street shoe". If they happen to be a bit larger order 2 or 3 mm aqua socks. Hope this helps.

My son is now 27 months old and it does not fit him with his shoes on anymore. He is approximately 93cm tall.

They would be too small for her feet then. My daughter is a 12-13 and they are way too small for her. Only her 2 yr old sister can wear and enjoy them.

This item is adjustable from 23.5 up to 31.5. It is an excellent product for those people who have sensitive feet!

actually I found a shop with same brand and I let her to try size 14- 16 just fit her ,she is 13 years old and her body weight 40 kg . and when she tried size 18-20 it was so big . so take care of the size .

For a 2 year old maybe fits a little loose, especially the bottom. I suggest for children from 3 years of normal size. I have not bought the shoes, so I can not comment about it.

A 20" balance bike, the Super Glider, would be a better fit for this child.

They are about 1/2" longer for my granddaughter's foot. She just turned 4 so a 1/2" isn't too bad. At least she will have them for a couple of seasons. She's absolutely thrilled with them.

I think you should try the Aqua Tot - especially since she's been doing lessons. My daughter is similar in height/weight and it worked perfectly for her so she can move around more than if she was in an inflatable.

The insert material wasn't thick and therefore, regular size shoe worked for my brother. His feet are not wide.

I think there is another brand that might work better for little toes. I don't remember the name though, sorry. But it is one I gave a negative review to... ;) Keep searching, you may find one. Eventually everything ends up on Amazon!

I bought one size bigger than my kids shoe size. If necessary they can wear two pairs of socks.......they will last a bit longer..

I think it will be too small for either of your sons. L size goes up to 1. According to this conversion chart http://www.dancesport.uk.com/shoes/conchart.htm, 34 would be US size 2; 37 would be US size 4.5.

The Footminders web site says, "Kids (K) and Small Kids (SK). In general, the SK orthotic is suitable for children from about 4 1/2 years of age to about 6 years, and the K orthotic will fit children from 7 to 9." My daughter was 9 years old and wearing a size 4 shoe and I purchased the K (1-3 1/2) and they fit perfectly. The SK (Youth 11-13) is for a smaller foot. Footminders also has sizes larger than these too. The SK is the smallest, then K, and then the next size up would be their X-Small (http://www.footminders.com/footminders-orthotics-for-kids-children.html).

It says for ages 5 and up (51-54cm or 20.1-21.3 inches) , although I do believe you can get smaller ones. Ask the seller.

I found these to be too tight for my 6 month old. I think they'd be too tight for a a school aged child. We used them for 15 minutes and haven't tried them again since.

These worked perfectly for my little one who is about 7 1/2 pounds. I did find that I needed to leave "one" that was soiled to encourage her to use it, until she become used to the feel of it under her feet.
