Question: My son's show size is 11, he is 4 years old what size should i get M or L?
Document: I ordered these skates in the large size for my grandson, who was turning 8-years-old. The large size was too small. There should be a more specific way of sizing the skates. He was disappointed, and now I will either waste money returning the skates, or have to give them away to someone else and get my grandson another birthday present.
My son wears a size 1. I bought the large size (2-4). They were a little snug on the smallest setting, so we expanded them a little and they are a perfect fit. I suspect we will get a great deal of use out of them since they expand; however, they definitely will not fit until size 4. If your child wears a size 4, they probably will not fit at all.
These skates I bought for my 6 year old and he loves them. They are easy to get on and the size adjusting is easy and brilliant.
Bought this skate for my son who is 5yrs. old. He wears a size 11 in a shoe and this fits him great. The adjustment mechanism works well, and holds (so far) in the size that we have set. My son loves his skates. They roll well and are quiet. The kids have put these skates to the test (skating on carpet, tile, wood) and nothing fazes the skate.
We bought these skates and they seem to be working great. I didn't spend a fortune on the learning skates by fisher price, by they time I thought about buying roller skates for my 4 year old the fisher price skates didn't seem like they would fit long enough to worth it. We needed a size12 skate and the fisher price skates only go up to size 12.
These are great quality and I like how they adjust....my son wears a size 11 or 12 childrens.....these are great.
my 7 years old son loves it, it looks great and he already learned how to skate. great deal !
My son got these skates for his birthday and he loves them. They appear to be of good quality and well made. The latches make them very easy to get on and off and they stay nice and snug to support his ankles. He has used them every day for about 4 days so far and they are holding up well to falling and pounding. The only reason I gave this 4 stars is because they run a little small.
We bought these for my son who had a smaller set of skates by the same company. Those skates were 11,12,1 in sizes. These are 12,1,2. The skates are great and easy to adjust, but I don't understand why they overlapped the two size ranges so much.
My 4 year old son loves these. They are great quality, durable and spin well. I can see him wearing them a long time.
Answer: yes
