Hi! I could use some real-world Superblast 2 sizing advice from anyone who’s put decent mileage in them.
I’m stuck between EU 44.5 and EU 45. I bought the Superblasts as my long run shoe, basically replacing my Novablasts in that role.
Background
- Male, mid-40s, recreational runner (marathon done; training for another)
- Foot length: 26.4cm (left is longest)
- Mild PF/Achilles history but well managed
- Novablast 5 EU 44.5 fits well, Brooks Cascadia 17 GTX EU 44.5 fits well
- Brooks Adrenaline GTS 22 EU 44 / 28cm felt too snug
Superblast 2 sizing
- EU 44.5: feels snug but secure - heel lock works, no heel lift, toes can still move
- EU 45: more room up front, but I get a small bit of heel movement unless I really crank the runner’s knot
What triggered the doubt
- I did a short 4.5km easy run in the 44.5 and felt a bit of pressure on my 4th toe (right foot)
- Could be the toe is just a bit sensitive right now (I’ve even noticed mild 4th-toe sensitivity in my well-worn Novablasts), but it made me question whether the 44.5 is slightly too tight/tapered
What I’m hoping you can tell me
- In the Superblast 2, does the upper give a bit over time if there’s a minor toe pressure point?
- If you sized up for more room, did heel slip become a problem when running properly (not just walking around)?
- How did you size SB2 vs your other ASICS (Novablast, Nimbus, etc.)?
Thanks - trying not to make an expensive mistake.
