I just bought a pair of these. I previously used the Speed Solutions a few years ago.
I bought a pair of GR8's in April. They've been durable but it's about time to go.
I noticed with the GR8's, my foot speed chasing drop shots and let cords had significantly gotten slower. I never used to have any issues turning on the jets to get those let cord balls and droppers. Again, great stability (I've been using them on the pickleball court too), but man running down balls on a full sprint going downhill and playing defense has become a lot more difficult.
I'm interested to see how light these Solutions are, and if chasing those droppers will be more smooth for me again.
Initial impressions after using for about 5 hours (first day 2 hours of hitting, second day 1 hour of hitting and 2 hours of teaching all 3 hours straight).
MAN were they stiff out of the box.
The last time I had Solution Speeds (2021) they I used a runners knot (extra holes) and I didn't have an issue.
Bur my feet were in pain the whole session on Sunday. And some of it yesterday.
I removed the runners knot from my left shoe but kept it on the right, and it helped alleviate some of the tightness on the left shoe.
The upside is I definitely feel faster and wasn't having issues chasing wide balls and sprinting for droppers that I wasn't getting even close to previously.
I'm hoping this break in period with the shoes is brief because I do like the fact I am faster.
I'm only 5"7, so I absolutely need my speed when I'm hitting against tallers guys with heavy spin and power from baseline.
The GR8's had great stability and firmness. Never once had any issues in the 6 months I used them (the break in period wasn't as rough as these).
But I need my speed. And if you have good footwork and coordination you don't have to worry about injuries or ankle rolling, so I will sacrifice some of the stability/firmness for the lighter and speedier shoe.
Sprinting to short angle balls and drop shots was a noticeable difference, even if once the point stopped my feet were feeling suffocated. Lol.
