Background

Encoded by the ob (obese) gene, Leptin is an adipose-derived cytokine that suppresses appetite and increases thermogenesis. The absence of leptin (or its receptor) leads to uncontrolled food intake and resulting obesity. Leptin exerts its anorectic effect via signaling through a hypothalamic receptor termed OB-R. Leptin has been shown to reduce body weight, food consumption, and plasma glucose levels in various in vivo models. Recombinant Human Leptin is a 16.0kDa protein containing 146 amino acid residues.

Comfortable boy shoes
Size: 4 Wide Big Kid, Color: Black/White
My son’s favorite sneakers. I think this is a fourth pair we ordered as he grows. Lightweight but mostly wide enough to be comfortable. I wouldn’t buy them for a full price but they are often in sale and then it’s great value for my money.

Merrell Unisex Child Wind 3.0 (4 Big Kid, Silver/Purple)Merrell Unisex Child Wind 3.0
Size: 4 Big Kid, Color: Silver/Purple
These shoes are cute and fit true to size! My daughter loves them. However these are Saucony shoes, NOT Merrell. I guess these are owned by the same company (I had to look it up) but are still very much so separate brands so I think its a bit misleading to have them labeled Merrell on the listing but Saucony on the actual shoes.

Good - but not really wide
Size: 2.5 Wide Big Kid, Color: Black/White
I purchased these for my son (6 Years old). He has quite a wide foot, so we purchased these because they said they were wide. They were not. Overall the style is nice, but in the end we had to return them and we wound up with some Sketchers wide sneakers that truly were wide.

Great quality, fit as expected, comfortable, and a great value for the money! I wear a size 4 widechildren’s shoe, which makes it very hard to find footwear that fits. And these fit just right!
