Changes

* '''Outsole'''. The Paradigm has harder rubber over most of the contact surface of the soul. This reduces the wear on the outsole, but there are areas around the little toes that are exposed midsole which will wear more quickly. See the picture at the top right for more details.

* '''Shape'''. The shoe is the classic Altra shape, which follows the outline of the human foot much better than other makes. This gives it a broader toe box, but I find there is not enough height for my toes and [[Shoe Modifications| I still have to cut the toe box open]].

* '''Tongue'''. The Paradigm has a classic tongue rather than a tongue-less sock style of upper. The tongue is partially attached on the inside edge to keep it positioned, which I really like. The tongue has minimal but adequate padding.

* '''Lacing'''. The flat laces work well and remained tied. Like many Altra shoes, I find the position of the uppermost eyeholes a little old, with the top hole too high and the next hole a little too low. The shoes come from the manufacturer laced in a way that indicates they think you should do a [[Lacing#The Heel Lock| "heel lock" style of lacing]], which I hate. I find that approach is very hard to get the tension right.
