imo aigle parcours iso are a decent wellie good thick rubber and a plenty of neoprene. ive had mine 2 seasons now and they are still going strong, i brought a pair of le chameaus after someone told me they were the best wellies going and once you have owned a pair you wouldnt have any other brand. they lasted me 6 months they ripped easy.
my aigles have stood the test of time well and are the secound pair i have owned, and both pairs have lastet equally aswell.
