Those are them, they really havent changed those shoes much over the years so the number model of those doesnt matter.. Nimbus 14,15,16 etc... Hunting after older models is a good way to save some money.... Both have proven to be good shoes for me as far as comfort and durability...... With that said i agree with Ironwolf... Shoes are very individual and you should take advice loosly... Shoes that are not right for you will tear your feet to hell and make any distance running unbearable...but i would stick to the shoe companies that specialize in running shoes... Saucuny (no recommendations) brooks, asics some models NB ... I should have mentioned, to add to ironwolf, get out in stores, try different ones out.. Go to new balance and get Foot measured... Then order ones you liked from zappos.... Its going to be a trial and error thing... Example: Shoes i run in for 1-2 miles wont work for me at half and full marathon.. I run a half a size bigger on my marathon shoes and run shorter distances in racing flats... I prefer racing flats and have trained and ran one marathon in them but stopped running long in them because i run too many miles on concrete
