Because the socks have grip on the bottom
Maybe one price is with socks and the other is if you have to buy there socks.Like others have said you need grips on your socks so you will not slip.Also maybe the price difference might be one for kids the other for adults.I would call and ask them or go over there if you live close by this way you could ask them whatever questions you want and they can not put you on hold like a phone.
Not sure of price. You cannot wear any socks.must have the no slip on bottom or buy their socks
I do know they recommend grippy socks and not regular socks to avoid slips on the trampoline mats.
