In this case, looking to apply to running shoes per a recommendation

Bottle says:

Apply Pliobond contact cement on both surfaces. If absorbed apply
additional coats.
Allow cement to almost dry
Hold under pressure 10-15 minutes until dry, preferably overnight

Package says:

To clean dry surfaces apply a thin uniform coast to each surface.
Permit both to dry completely. If one surface is extremely porous,
apply a second coat and also permit to dry. When ready to assemble,
apply an additional coast to either surface and when tacky press
firmly together. Use pressure if possible during final bonding. The
resulting bond permits rapid handling but total cure strength develops
in about 7 days.

Any thoughts from previous experience? How would one apply pressure
when using on running shoes? Someone mentioned using heat during
application, how would that be done?

Thanks for all input

You can use large rubber bands to hold it together. I use bands that I
made from old bike tubes. Bands of any size can be made by cutting a
tube lengthwise.
You can let the glue set up as long as half an hour before bringing
together.
After mating the surfaces, turn the shoe over and beat on the sole
with a mallet or hammer over the entire surface. This is called
"stitching" in the industry.

Here is an alternate means of repairing without using pressure or
contact cement.
Shoe Goo, Plumber's Goop, RV Goop, Automotive Goop and so on are the
same formula. Buy the cheapest. It sticks very well to clean buffed
rubber. However, it does not wear very well. So find a source of
rubber such as pieces from old shoes, floor mats, or tire shreds. The
best wearing surface I have found is from sliced up tires. You want
pieces no larger than about 3/4" square. They can be of any shape and
can be smaller. Coat the surface to be repaired with a thin layer of
Goop. Then take your small repair pieces and coat each and place it on
the shoe, moving it back and forth to smear the glue. When the area is
"tiled" with pieces no closer than1/8" apart, fill in the missing
space with more Goop. The product dries by solvent evaporation so it
will shrink somewhat. After it sets, you can add more Goop to the
receded areas. Allow two days before running on the shoe. Fumes from
this glue are harmful to breath so work outdoors or take the shoes
outside to dry.
Goop is available at hardware stores and department store hardware
departments. Wal-Mart has the cheapest at about $2.97 for the Plumbing
Goop.
