I've never had ukayla but I know with cheaper boots they tend to lose their support in the heel and sag inwards, making it difficult or awkward to walk. Maybe look at some reviews online? I know many people like bear paws too
I have ukayla and sleep better that they were cheaper and uggs have had a lot if critics lately for skinning sheep for skin only. I am against fur and hide if no one eats it..leather is a waste product of beef and i know lots who like mutton (not me..ick)...why waste an animal??
Since it is a 10 year old who I assume will still be growing? Maybe I'd get the ukalas. I have uggs though, and would definitely recommend them. The fur is so much thicker ans softer than the ukalas.
