I don’t know. .
"They work and “feels like a normal shoe” when wader booties we’re on. Have the advantage of using studs for Ricky rivers. Would love to see less sharp stitching /edges on the inside of the tongue like on the freestone boots. If you need a kids wading boot, don’t shop around or try to make something else work. Just get these or if SIMMs would make them the freestone for even better comfort. If it’s u comfortable, how likely are kids going to be to want to continue doing something? A solid buy, but SIMMs - please make the freestone available in 5 size."
