Altra Paradigm 4.5


Inspired by the Badwater 135 ultramarathon, the Altra Paradigm 4.5 is ready for any distance.

Altra made the max-cushioned Paradigm 4.5 with an Altra EGO midsole for soft landings and a knit upper for all-over comfort.

What makes the Paradigm stand out, though, is the shoe’s subtle guidance. Designers added Stabilipods to enhance your foot’s three natural stability zones to prevent excess foot collapse and pronation, and they added a GuideRail for medial guidance when you need it.

Altra’s signature FootShape toe box gives the shoe a more natural fit that lets your toes splay naturally, and the ZeroDrop platform makes for an intuitive ride. Together, Altra’s technology makes the Paradigm 4.5 ideal for tired feet looking for an upgrade from traditional stability shoes.

This makes my 4th pair now!

Making the switch to Altra was one of the best decisions of my running life! I love the Paradigm's for the high mileage training I do on the dirt roads of Western Kansas. They hold up well and when I need to make a switch to Urban pavement or concrete they work just as well. Thank you Fleet Feet for making it easier for me to keep running!

Greatest show on Earth

Most comfortable and best fitting shoe I have ever ran in by far! Coming from someone who has had major re constructive surgery on one foot and multiple knee injuries, the roomy uppers allow my not so normal shaped foot to have plenty of room yet supportive in the right places and plenty of cushion too soften the impact for my knees. Soft like a Hoka but the room of being barefoot!

A great shoe for everyday walking

I find new things I like about these shoes every day. The wide toe box is a necessity, but there are lots of other features that are just nice. The stretchy shoelaces are cool, the ventilation is nice (except when stepping in puddles or dirt) and the colors are great.
